1. FINDING ANTIDERIVATIVE USING Mathcad 3 Figure 2. Integration Operators . Click the upper limit place holder, type 3 and click the lower limit place holder type 0. Now click the integrant place holder type x^5 -e^3x -sin(3x) notice you need it the space bar twice before -sin(3x) . Of course you need hit space bar once before entering -e^3x to exit the power mode. Finally in the integration variable place holder type x (see Figure 2 for the position of each place holder.) Now hit [=] key if in automatic mode or =[F9] otherwise to ﬁnd the value - 2 . 5 × 10 3 . a The second example is for ﬁnd indeﬁnite integral. Example 1.2 . Find the deﬁnite integral R ( x + 2 - e 3 x - sin (3 x )) dx. Solution At any blank space in the workplace of Mathcad , type [Ctrl][I], that is hold the [Ctrl] key and press [I] key to place the

Unformatted text preview: indeﬁnite integration operator Z d . Click the integrant place holder and type \x+2-e^3x-sin(3x) Notice you need to hit the space bar twice before-sin(3x) . Of course you also need hit space bar twice too before entering-e^3x to exit the square root operator. In general, you will need to hit the space bar as many times an need to escape the power(subscript, division, etc.) mode before you enter next term. The backslash \ brings up the square root operator. Finally in the integration variable place holder type x(see Figure 2 for the position of each place holder.) Now hold down[Ctrl] to type [.] key and click on...
