Find the simplified value of:
If 'θ' is an angle less than 120°, what is the value of 'θ' if it satisfies the equation 3cos2θ = 2 + sin2θ.
...If sin 28° = 15/17 , then tan 62° = ?
...
If sin(x + y) = 1 and sin(x - y) = (1/2), then what is the value of sinx cosx + 2sin2y + cos2y?
If 2ycosθ = x sinθ and 2xsecθ – ycosecθ = 3, then x 2 + 4y 2 = ?
If θ is an acute angle and sin θ + cosec θ = 2, then the value of sin2 θ + cosec2 θ is:
