The area under the curve y = cos(x) from x = 0 to x = π/2 is given by ∫(from 0 to π/2) cos(x) dx = [sin(x)] from 0 to π/2 = 1 - 0 = 1.

Q
Q: Calculate the area under the curve y = cos(x) from x = 0 to x = π/2.
Solution:
The area under the curve y = cos(x) from x = 0 to x = π/2 is given by ∫(from 0 to π/2) cos(x) dx = [sin(x)] from 0 to π/2 = 1 - 0 = 1.
Steps: 8
Show Steps
Step 1: Identify the function you want to find the area under, which is y = cos(x).
Step 2: Determine the limits of integration, which are from x = 0 to x = π/2.
Step 3: Set up the integral to calculate the area: ∫(from 0 to π/2) cos(x) dx.
Step 4: Find the antiderivative of cos(x), which is sin(x).
Step 5: Evaluate the antiderivative at the upper limit (π/2) and the lower limit (0): sin(π/2) - sin(0).
Step 6: Calculate sin(π/2), which equals 1, and sin(0), which equals 0.
Step 7: Subtract the two results: 1 - 0 = 1.
Step 8: Conclude that the area under the curve from x = 0 to x = π/2 is 1.
