```										Dear student,
Its a very simple question. You just have to use cosine and  sine formula.

If ABC is a triangle with sides a = BC, b = CA, c = AB, then prove that

In figure (i),
A < 90o

But from D BAE, we have

In figure (ii),
A > 90o

But from D BAE, we have

In figure(iii),

From (i), (ii) and (iii), we conclude that

Similarly, b2 = c2 + a2 - 2 ca cos B

All the best.

If sinx + sin 2 x + sin 3 x = 1,then find the value of cos 6 x - 4cos 4 x + 8cos 2 x.

Write sinx + sin 2 x + sin 3 x = 1, as: sinx + sin 3 x = 1 – sin 2 x Now squaring both sides, U would get, sin^6x + sin^4x + 3sin^2x = 1 and write each sin^2x to (1-cos^2x) => (1-cos^2x) ^3 ...
