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. ...
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 ...
