Tags Functions Theorem Trig functions In summary, the conversation was about finding the point c on the interval [π/5, 2π/5] where f'(x) = 0 for the function f(x) = sin5x. The equation for f'(x) was given as 5cos5x = 0, and the person was having trouble understanding how...
Sine and cosine live on the unit circle (radius 1). The other functions use a radius of secant (tan/sec) or cosecant (cot/csc).Q3: What's the swapped function?We make a mini-triangle by shrinking the original triangle down, and rotating so dx matches the side of length 1. It ...
