Example: Working with Sine and Cosine Integral Symbolic Functions
This example demonstrates the various representations of the sine and cosine integral functions, and of the hyperbolic sine and cosine integral functions.
The Sine and Cosine Integral Functions
1. Type in the series expansion representation of the sine integral function and evaluate it symbolically.
PTC Mathcad Prime evaluates this expression as the built-in Si function.
2. Use the series keyword to get the first six terms of the series.
3. Find the first 10 terms of the series.
4. Type in the series expansion representation of the cosine integral function and symbolically evaluate it.
PTC Mathcad Prime evaluates this expression as the Ci function.
5. Use the series keyword to get the first six terms of the series, and then to get the first eight terms of the series.
The Hyperbolic Sine and Cosine Integral Functions
1. Explicitly define the hyperbolic sine integral function, symbolically evaluate it, and find the first four terms of the series.
PTC Mathcad Prime evaluates this expression as the Shi function and finds the first four terms of the series expansion.
2. Use the Chi function to get the series expansion of hyperbolic cosine integral function.
