The correct answer is C
If 2cosA + secA = 2√2 , 0° < < 90°, then the value of 2(sec 4 A + cosec 4 A) is:
tan 4˚ × tan 43˚ × tan 47˚ × tan 86˚ = ?
If sinAo = (√3/2), then find the value of (sin245o + cos230o) × A ÷ 5 given that 0 < A < 90...
Find the value of (1 - sin2q) X (secq + tanq) X (secq - tanq) X cosec2q
If tan 4θ = cot 14θ, then find the value of cos 9θ.
