Example: Simplifying and Rewriting Expressions
Use symbolic keywords combine and rewrite to combine and rewrite expressions.
Keyword: simplify
1. Simplify the following expressions:
2. Insert the symbolic evaluation operator.
3. Insert the keyword simplify in the placeholder.
Keyword: combine
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.
Keyword: rewrite
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.
