Calculation Example

Let's work through some sample integral calculations:

Example 1: What is ∫x² dx?
Given Values:
Function = x²
Type = Indefinite Integral
Formula:
∫x^n dx = x^(n+1)/(n+1) + C
Step-by-Step Solution:
Step 1: ∫x² dx
Step 2: Apply power rule: x^(2+1)/(2+1) + C
Step 3: Simplify: x³/3 + C
Answer: ∫x² dx = x³/3 + C
Example 2: What is ∫₀¹ x² dx?
Given Values:
Function = x²
Bounds = 0 to 1
Formula:
∫ₐᵇ f(x) dx = F(b) - F(a)
Step-by-Step Solution:
Step 1: Find antiderivative: F(x) = x³/3
Step 2: Apply bounds: F(1) - F(0)
Step 3: F(1) = 1³/3 = 1/3
Step 4: F(0) = 0³/3 = 0
Step 5: 1/3 - 0 = 1/3
Answer: ∫₀¹ x² dx = 1/3
Example 3: What is ∫sin(x) dx?
Given Values:
Function = sin(x)
Type = Indefinite Integral
Formula:
∫sin(x) dx = -cos(x) + C
Step-by-Step Solution:
Step 1: ∫sin(x) dx
Step 2: Apply trigonometric rule
Step 3: ∫sin(x) dx = -cos(x) + C
Answer: ∫sin(x) dx = -cos(x) + C
Example 4: Calculate ∫x·e^x dx using integration by parts
Given Values:
Function = x·e^x
Method = Integration by Parts
Formula:
∫u dv = uv - ∫v du
Step-by-Step Solution:
Step 1: Let u = x, dv = e^x dx
Step 2: du = dx, v = e^x
Step 3: ∫x·e^x dx = x·e^x - ∫e^x dx
Step 4: ∫x·e^x dx = x·e^x - e^x + C
Step 5: ∫x·e^x dx = e^x(x - 1) + C
Answer: ∫x·e^x dx = e^x(x - 1) + C
