Question

(Sin30° cos30°)-(sin60° cos60°) ka maan

Answer 1

Answer:

$\large\boxed{0}$

Step-by-step explanation:

Remember to solve this problem, first only had to do is using sin and cos formula numbers from left to right.

Given:

sin(30°) cos(30°)- sin(60°) cos (60°)

Solutions:

First, identify of sin.

$\displaystyle \sin(30)^{\circ}=\frac{1}{2}$

Secondly, thing you do is identify solution of cos.

$\displaystyle \cos(30)^{\circ}=\frac{\sqrt{3} }{2}$

Thirdly, identify of sin.

$\displaystyle \sin(60)^{\circ}=\frac{\sqrt{3} }{2}$

Then, trivial identify cos.

$\displaystyle \cos (60)^{\circ}=\frac{1}{2}$

Solve.

Multiply fractions from left to right.

$\displaystyle \frac{1}{2}*\frac{\sqrt{3} }{2}-\frac{\sqrt{3} }{2}*\frac{1}{2}$

$\displaystyle\frac{1}{2}*\frac{\sqrt{3} }{2}-\frac{\sqrt{3} }{2}*\frac{1}{2}=\boxed{0}$

So, the correct answer is 0.
