Question

2 sin (90) + 3 cos (0)

Answer 1

sin (90)=1
cos (0)=1
2*1 + 3*1=2+3=5

Answer 2

To calculate the expression 2 sin(90) + 3 cos(0), let's break it down step by step:

1. sin(90): The sine function returns the value of the sine of an angle. In this case, sin(90) is equal to 1, as the sine of 90 degrees is 1.

2. cos(0): The cosine function returns the value of the cosine of an angle. In this case, cos(0) is also equal to 1, as the cosine of 0 degrees is 1.

3. Now, we have the values of sin(90) = 1 and cos(0) = 1. Substituting these values into the original expression, we get:

2 * 1 + 3 * 1 = 2 + 3 = 5.

Therefore, the value of the expression 2 sin(90) + 3 cos(0) is 5.
