Now we shall introduce identities expressing the trigonometric functions asmultiplesof x, i.e. 2x, 3s, 4x etc. in terms of the values of x. some of the commonly used identities are – sin 2x = 2 sin x cos x cos 2x = cos2x – sin2x ...
We can express cos2θ in terms of sin2θ:cos2θ−sin2θ=(1−sin2θ)−sin2θ=1−2sin2θThus, we can rewrite the numerator as:(1−2sin2θ)+cos3θ−sin3θ Step 5: Factor the difference of cubesUsing the identity a3−b3=(a−b)(a2+ab+b2), we can factor cos3θ...
