$|1| sin \alpha = \frac{p}{h} \\ \\ |2| .cos \: \alpha = \frac{b}{h} \\ \\ |3| .tan \: \alpha = \frac{p}{b} \\ \\ |4| cosec \alpha = \frac{1}{sin \: \alpha } = \frac{h}{p} \\ \\ |5|.sec \alpha \: = \frac{1}{cos \: \alpha } = \frac{h}{b} \\ \\ |6| .cot \: \alpha \: \: = \frac{1}{tan \alpha } = \frac{b}{p}$

{ here P stands for Perpendicular , B stands for Base and H stands for hypotenuse }

$= > sin {}^{2} \alpha + cos {}^{2} \alpha = 1 \\ \\ = > sec {}^{2} \alpha - tan {}^{2} \alpha = 1 \\ \\ = > cosec {}^{2} \alpha - cot {}^{2} \alpha = 1$

⬆These were the basic ones according to class 10☺
