Write the expression as the sine cosine or tangent of an angle calculator.

hello your question is incomplete here is the complete question

write the expression as the sine, cosine,  or tangent of an angle.

answer :

Step-by-step explanation:

To write the expression as the sine,cosine or tangent of an angle we will employ the trigonometry identity

 can be represented in the form of ;

sin( u + v ) = sin u cos v + cos u sin v --------- (1)

comparing equation 1 with the given expression

u = 60 and v = 15

therefore writing the expression in the form of the sine of an angle would be the answer

= sin( 60 + 15 )  = sin 60 cos 15 + cos 60 sin 15

hence sin ( 75 ) = sin 60 cos 15 + cos 60 sin 15

i don't even know man. edge inuity be messing with us. i had to ask a question too.
