Question

E valuate sin 60° cos 30° sin 30° cos 60° what is the value of sin (60°+30°) what can you conclude? ​

Answer 1

Step-by-step explanation:

Value of cos and sin depends on theta,

For eg : value of sin 30 = 1/2

Theta will be between 0 deg and 360 deg

Answer 2

Answer:

3/16 and 1

Step-by-step explanation:

sin60°=√3/2,cos30°=√3/2,sin30°=1/2,cos60°=1/2

√3/2×√3/2×1/2×1/2 = 3/16

sin (60°+30°)=sin 90°

sin 90° =1
