Find the area under the curvey=7x3from x = 1 to x = t. Area under a Curve: The area under a curve is given by the following integral formula: A=∫x1x2f(x)dx We have the function and the limit of integration is also given. Using the analogy of this formula, we...
Find the area under the curve y=sinx from x = 0 to x = b, where 0<b<π. Area By Integration: A definite integration of a function gives the area bounded by the function and the horizontal axis. We have to integrate the area of a vertical sli...
1. Set up the integral: The area A under the curve from x=0 to x=1 is given by: A=∫10xexdx 2. Use integration by parts: We will apply the integration by parts formula: ∫udv=uv−∫vdu Here, we can choose: - u=x (thus du=dx) - dv=exdx (thus v=ex) 3. Apply the ...
Curve Tracing Using Integration(applications of integration):The following outline procedure is to be applied in Sketching the graph of a function y = f (x) which in turn will be extremely useful to quickly and correctly evaluate the area under the curves. ...
