If you want to get an answer like 1/2X for d/dx(X^2), you will have to
purchase a CAS calculator like Casio's Algebra FX-2 or Classpad. TI series calculators also have CAS.
However, you can calculate the numerical values of derivatives and integrals only.
To calculate the value of a proper integral:
- Press the 'ON' key;
- Press the Integral key ;
- Enter your expression (example X^2+X-3 etc);
- Press the 'comma' key after your expression;
- Input the first limit after comma, input comma again after first limit;
- Close brackets;
- Press the equals key, display may return after a while with the answer.
for eg to calculate
∫xdx from 0 to 2, input as follows:
∫dx(X,0,2)
To calculate derivative at a point:
- Press Shift and then the integration key.
- Enter your function;
- Input comma;
- input the point at which you want to evaluate the derivative;
- Close bracket and press enter.
Example, to calculate d/dx X^2 at 3 input:
SHIFT+
∫dx key X^2,3)
Display looks like this: d/dx(X^2,3).
