Convert from cos(x) sin(x) cos ( x) sin ( x) to cot(x) cot ( x). 1: Graph of the secant function, f(x) = sec x = 1 cos x f ( x) = sec x = 1 cos x.S (sin A + cosec A)2 + (cos A + sec A)2 = (sin2 A + cosec2 A + 2sin A cosec A) + (cos2 A + sec2 A + 2 cos A . If sec 4A = cosec (A - 20°), where 4A is an acute angle, then the value of A is 22°.
