Find the maximum value of 18 sin A + 7 cos A.
If θ is an acute angle and sin θ + cosec θ = 2, then the value of sin2 θ + cosec2 θ is:
If cos2B = sin(1.5B + 48o), then find the measure of 'B'.
If (sin A + cos A) = √3 cos (90° - A), then find the value of cot A.
If 30sin4theta; + 45 cos4theta; = 18 . Then find the value of 216 cosec6theta; + 64 sec6
sin2 4˚ + sin2 6˚ + sin2 8˚ + sin2 10˚ + ……… + sin2 86˚ =?
What is the simplified value of the given expression?
2(sin² 15° + sin² 75°) + 4sin 30° - (2sec 60° + cot 45°)

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