of sin ( 45 degrees + \theta ) - cos ( 45 degrees - \theta ) – InterviewSolution

1.

of sin ( 45 degrees + \theta ) - cos ( 45 degrees - \theta )

Answer»

sin(45+theta)-cos(45-theta)= sin(45)- cos(90-45)= sin(45)-sin(45)=(1/V2)-(1/V2)=1

sin45 is 1/V2, cos45 is 1/V2 1/V2- 1/V2=0

it is correct answer
