trig 26
posted by hilde .
simplify to a constant or trig func.
1. sec ²utan ²u/cos ²v+sin ²v
change expression to only sines and cosines. then to a basic trig function.
2. sin(theta)  tan(theta)*cos(theta)+ cos(pi/2  theta)
3. (sec y  tan y)(sec y + tan y)/ sec y
combine fractions and simplify to a multiple of a power of a basic trig func.
4. (1/(1sin x)) + ((1/(1+sin x))
5. sin x/1cos x + 1cos x/ sin x
write in factoed form of a single trig func.
6. 12sin x + sin²x
7. sin x  cos²x  1
