Example: Simplifying and Rewriting Expressions
Use symbolic keywords combine and rewrite to combine and rewrite expressions.
Simplify Keyword
1. Simplify the following expressions:
2. Insert the symbolic evaluation operator.
3. Insert the keyword simplify in the placeholder.
Combine Keyword
1. Use the keyword combine to combine the following expression:
| The keyword combine does not affect the result. |
2. Add the modifier sincos to specify rewriting the result in terms of sine or cosine.
3. Use the keyword combine with other modifiers to combine more expressions.
Rewrite Keyword
1. Use the keyword rewrite to rewrite the following expression using specific types of identities:
PTC Mathcad returns an error because rewrite requires a modifier.
2. Add the modifier exp.
PTC Mathcad rewrites sin in terms of exponential functions.
3. Use the keyword rewrite with other modifiers to get the desired type of result.
