View Solution. cosec (90°−x) = sec x. ∴ x = nπ or x = 2mπ ± 0 ∴ the required general solution is x = nπ or x = 2mπ, where n, m ∈ Z. hope this helped!
We could simplify this answer a bit by using some basic trig identities: = cosx( sinx cosx) +sinx( 1 cos2x) = sinx + sinx cosx ( 1 cosx) = sinx + tanxsecx. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.
sin x = tan x ∴ sin x = sinx/cosx ∴ sin x cos x - sin x = 0 ∴ sin x (cos x - 1) = 0 ∴ sin x = 0 or cos x = 1 ∴ sin x = sin 0 or cos x = cos 0.5.2

Explanation: If we write cot(x) as 1 tan(x), we get: cot(x) +tan(x) = 1 tan(x) + tan(x) Then we bring under a common denominator: = 1 tan(x) + tan(x) ⋅ tan(x) tan(x) = 1 + tan2(x) tan(x) Now we can use the tan2(x) +1 = sec2(x) identity: = sec2(x) tan(x) To try and work out some of the relationships between these functions, let's represent the
