How do I know what angle inverse Sin / Cos / Tan actually returns?
I understand how to use inverse Sin / Cos / Tan to get the angle, but what I don't understand is how I know which angle it returns. If we have a right angled triangle like this emoji: 📐 How do I know if inverse Sin / Cos / Tan returns the angle to the right of the 90 degree angle or the above it? Am I overthinking this?
besides practice, any tips on remembering how to use Sin, Cos, Tan in Right Angle Trig?
Hello all, this weeks online Elementary Algebra homework subject was Right Angle Trigonometry. It started out surprisingly easy, Multiply X (Opposite, Adjacent or Hypotenuse measurement) by Sin/Cos/Tan of Y degrees to find the desired variable. Once division got added into it, then I got confused on how to differentiate between using multiplication or division to find the solution. I end up writing all the information given to me and drawing diagrams when they're not given, and mess around until I either enter the correct answer in the online program, or cave in and ask the program for help. I seen a video on youtube that showed 3 triangles with the letters SOH, CAH and TOA to help you figure out how to solve problems based on given information. I feel comfortable now deciding on whether Sin, Cos or Tan is required, but am still confused on whether I need to multiply or divide the given information to find the proper solutions. I also understand that I JUST learned this info, so I am ready to do more practice work to help me better understand it all. I'm just curious if theres any other tricks or pieces of advice to help me better understand it.
This relates to the post on the dual route platform 116, and the number obtained through π as 116.7168. Now I'm a novice at Sine , Cos and Tangent (and this is where I could do with some real technical assistance). Needless to say 32 is a massively significant number in the Migrator Model (the 492 finding and the distance in standard sectors between twin curve å and ß). Forgive the crude notation form, but test it on your own calculator - XXX SIN of 116 = 0.898794046 SIN -1 of 0.898794046 = 64 XXX COS of 116 = -0.43871146 COS-1 of -0.43871146 = 116 XXX TAN of 116 = -2.050303842 TAN -1 of -2.050303842 = -64 XXX SIN of 7168 = -0.529919264 SIN -1 of -0.529919264 = -32 XXX COS of 7168 = 0.848048096 COS -1 of 0.848048096 = 32 XXX TAN of 7168 = 0.624869351 TAN -1 of 0.624869351= -32 116 and 7168, as part of the dual route platform found in π, share a correlation to 32 (or x 2 as 64) through this method using the inverses (arcsine etc), pointing to the geometric (circle and ellipse) structures in the mathematical signifiers. https://www.reddit.com/MigratorModel/comments/z8oizc/the_dual_lockdown_route_platform_inside_pi_update/
Question1: are sine, cosine and tangent just the names, i.e. labels for the ratios of the sides of triangles? Question2: how are the ratio's of triangles mapped to angles (degrees), i.e. how are the inversed versions of sin(), cos(), tan() implemented?
How did people originally figure the value of Pi and various sin, cos and tan value?
I am reviewing some precalculus and I just wonder how did people figure out the values of pi and various sin, cos and tan angles? I know pi = circumference divided by diameter. Sin 90 degree is 1, then sin 66 is 1 x 66/90 ? I know some ways to calculate pi but what about before those methods? Did people just use a string and measure the length? What about the sin, cos and tan angles? I know the values of some special angles. Did people just divide the value manually to get the rest of the values, such as sin 64 degree?
[trigonometry] Inept math slug bemused by sin/cos/tan, desires salvation
I am completely retarded when it comes to math, honestly. Upon beginning my programming adventures w/ a game development focus i knew intuitively I would hit a wall eventually and need to learn it. I think i finally hit the wall. I understand that vectors can be analyzed using trigonometry because every vector can be represented as a right triangle. I am basically trying to calculate the θ [theta?] degrees using a few known values of a vector: opposite [-1] and adjacent [1]. The application: i have a player in a game which can move octagonally [in 8 directions], this is already functioning but there is a flaw in the design: the player moves diagonally at a faster speed. basically the x increment of the vector is 1, and the y is -1, both inputs register simultaneously, which would move to the top-right, but this would result in the tangent of the vector being... not 1, moreso like 1.42 using Pythagorean theorem something like that because they both increment simultaneously each frame refresh. the first step to solving this is to understand exactly what direction the player is actually moving. I am basically trying to calculate the θ [theta?] degrees using a few known values of a vector: opposite [-1] and adjacent [1]. so the tan function for this would need to be inverse, right? so i input that jazz into a scientific calculator and i always just get 1.. whereas i am expecting to get a degree (45°) as an output from the function.
I tried using the sum of angles formula for the lhs and the sum to product formula for the rhs and got: sin(x) cos(20°) + cos(x) sin(20°) = 2 cos(x) cos(10°) Then I divided by cos(x) cos(10°): tan(x) [cos(20°) / cos(10°)] + [sin(20°) / cos(10°)] = 2 Now I don't know how to continue. What should I do?
what are you doing when you use sin, cos, tan in an equation in your calculator?
i’m currently in calculus and my biggest problem in math is i’m always thinking why and i’m too stupid to understand the why, but it’s hard to do things when i don’t know why. i’ve done discrete maths so i’ve done some proofs and now i think it’s helped my brain think theoretically a little bit. so what am i doing when i do something for example like sin(35) * 4 sin is opposite over hypoteneuse right? so does the calculator do sin of 35 * 4? and then it’s either in degrees or radians? and now that i think about it what do sin cos and tan even mean like i know what they are but…huh? and they make graphs? i do not understand why tangent graphs look like that? and why do we use the word tangent when we’re talking like going on a tangent? i think trig was my favorite part of pre calculus but i don’t think i understood why i did most of it.
