The half-angle identities are the last of the identities we study. 9.1 Indeterminate Forms and L'Hopital's RuleĬontinuing to expand our arsenal of useful trigonometric formulae, in today's lesson we study the half-angle identities which expand trig functions of a half-angle such as `cos(x/2)`.Ĭaution: To avoid a common error, when determining the sign of the answer from a half-angle formula, remember that it is based on the quadrant of the half-angle, not the quadrant of the whole angle.5.2 Integrals Resulting in Inverse Trig Functions.5.1 Integrals Resulting in Logarithmic Functions.5.0 Review of Transcendental Functions and thier Derivatives.4.7 Integration by Substitution & Definite Integrals.4.6 Integration by Substitution & Indefinite Integrals.4.5 Mean Value Theorem for Integrals & Average Value.4.3 Electronic Evaluation of Riemann Sums and Definite Integrals.4.2 Riemann Sums, Definite Integrals, and Area Under the Curve.4.1 Antiderivaties & Indefinite Integrals.3.3 First Derivative Test & Increasing-Decreasing Functions.2.11 Derivatives of Inverse Trig Functions.2.7 Derivatives of Exponential and Logarithmic Functions.2.4 Product Rule, Quotient Rules, & Deriv.9.2 Products and Quotients in Trig Form.9.1 Trigonometric Form of Complex Numbers.6.4 Equations Involving Inverse Trig Fns.5.5 IDs Involving Inverse Trig Functions.4.4 General Equation & Graph to Equation.4.3 Vertical Translations & Phase Shift.
