Ex

cosx = sinx Mr F says: => tan x = 1 ....

sinx = cscx Mr F says: ${\color{red} \Rightarrow \sin^2 x = 1 \Rightarrow \sin x = \pm 1 \, ....}$

csc^2x = cotx +1 Mr F says: ${\color{red} \Rightarrow 1 + \text{cot}^2 x = \text{cot} x + 1 \Rightarrow \text{cot}^2 x = \text{cot} x \Rightarrow (\text{cot} x) (\text{cot} x - 1) = 0 \, ....}$

any help would be great thank you
