I'll do a few of them to give you a start!
42.
LHS = 1  csc(x)sin³(x)
= 1  1/sin(x)*sin³(x) [Def. of csc(x)]
= 1  sin²(x) [Cancel a sin(x)]
= cos²(x) [sin²(x) + cos²(x) = 1]
=RHS
43.
LHS = (1 + cot(α))²  2cot(α)
= 1 + 2cot(α) + cot²(α)  2cot(α) [Expand]
= 1 + cot²(α) [Cancel like terms]
= csc²(α) [Pythagorean Identity]
= 1/sin²(α) [Definition of csc(α)]
= 1/(1cos²(α)) [Pythagorean Identity]
= 1/((1+cos(α))(1cos(α))) [Difference of 2 Squares]
= RHS
44.
RHS = (1sin²(x))/(1sin(x))
= (1+sin(x))(1sin(x))/(1sin(x)) [Difference of 2 Squares]
= (1+sin(x))(1sin(x))/(1+sin(x)) [sin(x) = sin(x) odd symmetric function]
= 1  sin(x) [Cancel 1+sin(x)]
= LHS
Ok, I hope this gives you a start! For some of the other ones, these identities may help,
sin(x ± y) = sin(x)cos(y) ± sin(y)cos(x)
cos(x ± y) = cos(x)cos(y) ∓ sin(x)sin(y)
Please pick for best answer!
