Trigonometry
Use identities and CAST-style interval thinking to find all solutions. Always check the required range before giving final answers.
sin, cos, tan
Remember
One principal answer is rarely the full answer.

Logarithms
Logarithms rewrite index statements. Use log laws to solve exponential equations and to linearise relationships.
a^x = b <=> x = log_a b
Remember
Keep bases positive and not equal to 1.

Integration
Integration reverses differentiation and can find areas under curves. Remember the constant of integration for indefinite integrals.
integral f(x) dx
Remember
Differentiate your answer to check it.
