The Science which studies the crust of the

cos (sec^-1 x) is equal to –

If sec²x + csc²x = 10, find the value of tan²x + cot²x.

If cos θ + sec θ = √2, then the value of cos³ θ+ sec³ θ is:

If √3 tan 2θ – 3 = 0, then find the value of tanθ secθ – cosθ where 0 < θ < 90°

If x tan 60° + cos 45° = sec 45° then the value of x² + 1 is

What is the value of [(tan 5θ + tan 3θ)/4 cos 4θ (tan 5θ – tan 3θ)]?

The Value of (sin38˚)/(cos52˚)+ (cos12˚)/(sin78˚)- 4cos²60˚ is

If sin(x-y) = 1  and cos(x+y) = 1 /√2  then what is measure of angle x.
