Question

the value of sin 60 degree cos 30 degree minus Cos 60 degrees sin 30 degree is​

Answer 1

Step-by-step explanation:

sin60° cos30°- cos60° sin30°

$\frac{ \sqrt{3} }{2} . \frac{ \sqrt{3} }{2} - \frac{1}{2}. \frac{1}{2} \\ \frac{3}{4} - \frac{1}{4} \\ \frac{1}{2}$

Answer 2

Answer:

sin60°cos30°-cos60°sin30°

sin(60°-30°).

sinAcosB-cosAsinB=sin(A-B)

sin(30°)

1/2

alternative:

sin60cos30-cos60sin30

√3/2×√3/2 - 1/2×1/2

3/4 - 1/4

3-1/4

2/4

1/2
