1+tan 2 x = sec 2 x cosec 2 x = 1 + cot 2 x these three identities are of great importance in mathematics, as most of the trigonometry questions are prepared in exams based on them. therefore, students should memorise these identities to solve such problems easily. sum and difference ...
By the trigonometric identities, we know that sin2𝜃 + cos2𝜃 = 1. But let us prove this using the trigonometric table. sin230o+ cos230o= (½)2+ (√3/2)2= ¼ + ¾ = 4/4 = 1 Practice Questions Find the value of tan 45o+ sec 30ocos 30o. ...

Integration using trigonometric identities is explained here in detail with examples. Visit BYJU’S to learn how to perform integration operations when the integrand involves trigonometric function.
Now if we substitute suitable values in identities (1), (2), (5) and (6), we have the following: cos (π/2 + x) = -sin x sin (π/2 + x) = cos x cos (π± x) = – cos x sin (π– x) = sin x sin (π + x) = – sin x ...
