Question:
If cos(2/3x) + cos(3/4x) = π/2 (x > 3/4), then x is equal to √145/12, √145/10, √146/12, √145/11
√14510
√14612
√14512
√14511
Solution:
The correct option is A √145/12
cos(2/3x) + cos(3/4x) = π/2 (x > 3/4)
√14510
√14612
√14512
√14511
The correct option is A √145/12
cos(2/3x) + cos(3/4x) = π/2 (x > 3/4)
