Question

sin60.cos30+sin30.cos60 value ni ganimchdi. sin(60+30) value find cheyamdi​

Answer 1

Answer:

$\red {sin60 cos30 + sin 30 cos60}\green {= sin(60+30)}$

$\boxed {\pink { sinAcosB + sinBcosA = sin(A+B)}}$

Step-by-step explanation:

$sin60 cos30 + sin 30 cos60$

$= \frac{\sqrt{3}}{2} \times \frac{\sqrt{3}}{2} + \frac{1}{2} \times \frac{1}{2}\\= \frac{3}{4} + \frac{1}{4}\\= \frac{4}{4} = 1\: ---(1)$

$sin(60+30) =sin90\\=1 \: ---(2)$

Therefore.,

$\red {sin60 cos30 + sin 30 cos60}\green {= sin(60+30)}$

$\boxed {\pink { sinAcosB + sinBcosA = sin(A+B)}}$
