Integration by Using a Suitable Substitution Example Two
The mathematical solution explains how to use the substitution x = sin θ to find the exact value of an integration. The steps required to change the subject of the integration, including changing the values of the limits is explained. The final integral uses the fact that the differential of tanθ is equal to sec[sup]2[/sup]θ with the solution being given in surd form.
The graphical solution explains how to use the graphic calculator to verify the value of integral found in the mathematic solution. The calculator leaves the solution in surd form.
