Trig Function Reduction Formula
Trig Function Reduction Formula. Reduction formulae for function values of 90°±θ. Derivatives of basic trigonometric functions.
We need to go back, right back to first principles, the basic formula for derivatives and we can bring sin(x) and cos(x) outside the limits because they are functions of x not δx.

Because the problem requires the reduction of sin4 x, you must. Video showing how to derive trigonometric identity easily. For formulas to show results, select them, press f2. Now i have two squared trig functions, i can take either in the form of 1 + squared trig function but either way i get a power of 4 and nothing has gotten more simple.
