Prove that: (sin θ - 2 sin3 θ/2 cos3 θ - cos θ) = tan θ. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries.

for some value of x, cos 2 (x)+sin 2 (x) is 1. The latter property is quickly established: taking x=0, cos(x)=1 and sin The first shows how we can express sin θ in terms of cos θ; the second shows how we can express cos θ in terms of sin θ. Note: sin 2 θ-- "sine squared theta" -- means (sin θ) 2. Problem 3. A 3-4-5 triangle is right-angled. a) Why? To see the answer, pass your mouse over the colored area.

where sin 2 θ means (sin θ) 2 and cos 2 θ means (cos θ) 2. This can be viewed as a version of the Pythagorean theorem, and follows from the equation x 2 + y 2 = 1 for the unit circle. This equation can be solved for either the sine or the cosine:

U =2x dv =sin 2x dx. Du =2 dx v = cos 2x.
