Question

evaluate the following integral ​

Answer 1

Answer:

solve the indefinite integral trying to find the Primitive (or anti-derivative) of your integrand; this is a function that DERIVED will give you

sin

(x):∫sin(x)dx=−cos(x)

After that we use the Fundamental Theorem of Calculus where, basically, we take our Primitive, we stick in first our upper extreme

π/2

then the lower one

0

and subtract the values we obtain:

−cos(π/2)−(−cos0))=1

so we get:

∫π/20 sin(x)dx=1

Therefore, the answer is 1.
