Thefunctions sin x and cos x can be expressed by series that converge for all values of x: These series can be used to obtain approximate expressions for sin x and cos x for small values of x: The trigonometric system 1, cos x, sin x, cos 2x, sin 2x, . . ., cos nx, sin nx,constitutes an orthogonal system of functions on the interval
Answer(1 of 10): Sin^4(x)+Cos^4(x) =Sin^4(x)+Cos^4(x)+2sin^2(x)Cos^2(x)-2sin^2(x)cos^2(x) =(Sin^2(x)+cos^2(x))^2-2sin^2(x)cos^2(x) =1-2sin^2(x)Cos^2(x) =1-2
Youcan put this solution on YOUR website! sin (x) = 1/3. cos (x) = sqrt (8)/3. not sure how you're supposed to find this, but one way is to use the trigonometric identity of sin^2 (x) + cos^2 (x) = 1. this becomes (1/3)^2 + cos^2 (x) = 1. subtract (1/3)^2 from both sides of this equation to get: cos^2 (x) = 1 - (1/3)^2.

SinX minus co sign X. Times. I'm going to switch the order around CAen expose co sign X. This really is a difference of squares that this is Science squared X minus co sine squared X. Okay, that's a difference of squares. Now if we take out a negative one in common factor out a negative one don't have negative one equal.
