What is the simplified value of the given expression?
4(sin² 20° + sin² 70°) + 2sin 30° - (2sec 60° + cot 45°)
If 17sin A = 8, where 0
tan 20Ëš x tan 23Ëš x tan 67Ëš x tan 70Ëš = ?
If 3 tan X + cot X = 2√3, then find the value of 6 tan2 X + 2 cot2 X.
If 2ycosθ = x sinθ and 2xsecθ – ycosecθ = 3, then x 2 + 4y 2 = ?
If (3cos A - sin A) = 2 cos (90° - A), then find the value of cot A.
- Find the maximum value of (9sin A + 12cos A).
- If 2cos²A + 3sin²A = 13/5, then find the value of (sec²A - 1)
- If sin 2a = (1/2), then find the value of (sin a + cos a).
- If sin (3A − 2B) = (√3/2) and cos (A + B) = (1/2), where 0° < A, B < 90°, then find the value of ‘A’.
