1.1 Trigonometric Functions The term Fourier analysis originally refers to the possibility to approximate functions (up to scaling) in the open unit interval I≔]−1/2,+1/2[ by linear combinations of trigonometric functions (1)t0(x)≔1,t2n(x)≔2cos(2πnx),t2n−1(x)≔2sin(2π...
I keep stumbling on use cases that need trigonometric functions to be solved, and I always have to resort to JS or a preprocessor for them, which is a pain. Basically almost any time you need to match two things and angles are involved. ...
Figure 5. The six trigonometric functions are periodic. Just as with algebraic functions, we can apply transformations to trigonometric functions. In particular, consider the following function: f(x)=Asin(B(x−α))+Cf(x)=Asin(B(x−α))+C. In (Figure), the constant αα causes a...

Examples 4sin 2 x + 5 = 6, 3tan 2 x – 9 = 0 TYPE 2: Equations involving 2x, 3x, etc. but no other trigonometric function. Examples 3sin 2x – 1 = 1, 3tan(3x – 30) + 2 = 1 TYPE 3: Equations involving 2x and another trigonometric function i.e. equations...
I'm trying to implement inverse trigonometric functions in a C# application. Obviously I'm not talking about simple inverse sin, cos and tan seeing as those are all provided by the Math class. What I'm looking for is the inverses for sec, cosec and cotan:...
