cos(x)/(cos(x) + two) + sin(x)^ two /(cos(x) + two)^ two = zero
co sinus of e of (x) divide by ( co sinus of e of (x) plus 2) plus sinus of (x) squared divide by ( co sinus of e of (x) plus 2) squared equally 0
co sinus of e of (x) divide by ( co sinus of e of (x) plus two) plus sinus of (x) to the power of two divide by ( co sinus of e of (x) plus two) to the power of two equally zero
cos(x)/(cos(x) + 2) + sin(x)2/(cos(x) + 2)2 = 0
cosx/cosx + 2 + sinx2/cosx + 22 = 0
cos(x)/(cos(x) + 2) + sin(x)²/(cos(x) + 2)² = 0
cos(x)/(cos(x) + 2) + sin(x) to the power of 2/(cos(x) + 2) to the power of 2 = 0
cosx/cosx + 2 + sinx^2/cosx + 2^2 = 0
cos(x) divide by (cos(x) + 2) + sin(x)^2 divide by (cos(x) + 2)^2 = 0
