below. B $ C means ‘C’ is the husband of ‘B’ B @ C means ‘C’ is the mother of ‘B’ B + C means ‘C’ is the sister of ‘B’ B % C means ‘C’ is the father of ‘B’ B ÷ C means ‘C’ is the brother of ‘B How is R related to T in ‘Y ÷ R % I + V $ T’?Solution
If tan θ + cot θ = 5, find the value of tan²θ + cot²θ.
- If 2cos²A + 3sin²A = 13/5, then find the value of (sec²A - 1)
If cosec (2A + B) = 2 and cosec (A + B) = 1, find the value of (3A – B).
If cos4B = sin(B - 10°), then find the measure of 'B'.
If cot5A = tan(3A-14˚), find the value of A? Given that 5A and 3A-14˚ are acute angles.
If tan A = 1/√3, then what will be the value of sin⁴ A?
Evaluate the following:
sin 50° × cos 20° − sin 20° × cos 50°
If tan A = 1 and tan B = √ 3, what is the value of cos A . cos B - sin A . sin B?
- If 4cos²A + 5sin²A = 4.5, then find the value of (sec²A - 1)
If (2sin A + cos A) = 3sin A, then find the value of cot A.
