Question

sin (45 + theta) minus ( Cos 45 -
theta)​

Answer 1

we know,

cos(theta)=sin(90-theta)

Therefore ,

Sin(45+Theta)-sin(90-45+theta)

sin(45+Theta)-sin(45+theta)=0

Answer 2

Answer:

0

Step-by-step explanation:

sin ( 45 + theta) = cos ( 90 - (45 + theta) = cos (45 - theta)

Substitute this in the given equation ,

=> cos ( 45 - theta ) - cos ( 45 - theta )

=> 0 [ since the two quantities are same ]
