S i n θ = \frac{p e r p e n d i c u l a r}{h y p o t e n u s e} = \frac{y}{r}

C o s θ = \frac{b a s e}{h y p o t e n u s e} = \frac{x}{r}

T a n θ = \frac{p e r p e n d i c u l a r}{b a s e} = \frac{y}{x} = \frac{S i n θ}{C o s θ}

C o t θ = \frac{b a s e}{p e r p e n d i c u l a r} = \frac{x}{y} = \frac{C o s θ}{S i n θ}

S e c θ = \frac{h y p o t e n u s e}{b a s e} = \frac{r}{x} = \frac{1}{C o s θ}

C o \sec θ = \frac{h y p o t e n u s e}{p e r p e n d i c u l a r} = \frac{r}{y} = \frac{1}{S i n θ}
