Find the exact value of cos120°
- If sin (3A − 4B) = (1/2) and cos (A + B) = (√2/2), where 0° < A, B < 90°, then find the value of ‘A’.
If cot A = √3, then what will be the value of sin4 A?
If θ is an acute angle and sin θ + cosec θ = 2, then the value of sin2 θ + cosec2 θ is:
What is the simplified value of the given expression?
2(sin² 40° + sin² 50°) + 4sin 30° - (2sec 60° + cot 45°)
What is the simplified value of the given expression?
