Addition and Subtract of the Sine function With the sine function the sign between the expressions stays the same.
Addition and Subtract of the Cosine function With the cosine function the sign between the expressions change.
Addition and Subtract of the Tangent function Both are Rational expressions
Simplify Remember: sin(u-v)=sin u·cos v-cos u·sin v
Simplify Remember: sin(u-v)=sin u·cos v-cos u·sin v
Simplify Remember: sin(u-v)=sin u·cos v-cos u·sin v
