Trigonometric Functions
Positive and negative angles. Measuring angles in radians and in degrees and conversion
from one measure to another. Definition of trigonometric functions with the help of unit circle. Truth of the identity $𝑠𝑖𝑛^2{x}+cos^2{x}=1$, for all x. Signs of trigonometric functions. Domain and range of trigonometric functions and their graphs. Expressing $𝑠𝑖𝑛(𝑥 \pm 𝑦)$ and $𝑐𝑜𝑠(𝑥 \pm 𝑦)$ in terms of $𝑠𝑖𝑛𝑥, 𝑠𝑖𝑛𝑦, 𝑐𝑜𝑠𝑥$ & $𝑐𝑜𝑠𝑦$ and their simple applications. Deducing identities like the following: $ \tan (x \pm y)=\frac{\tan x \pm \tan y}{1 \mp \tan x \tan y}$, $\cot (x \pm y)$=$\frac{\cot x \mp \cot y}{\cot y \pm \cot x}$, $\sin \alpha \pm \sin \beta$=$2 \sin \frac{1}{2}(\alpha \pm \beta) \cos \frac{1}{2}(\alpha \mp \beta) $ $\cos \alpha+\cos \beta$=$2 \cos \frac{1}{2}(\alpha+\beta) \cos \frac{1}{2}(\alpha-\beta)$
