Type the argument or select the cell or range you want to insert in the function, and then type ) (a closed parenthesis) to complete the function.

Answer 2

Its quite easy ☺️☺️

Hope you know if we break any angle in the form 90+- theta or 270+-theta

ᴛʀɪɢᴏɴᴏᴍᴇᴛʀɪᴄ ʀᴀᴛɪᴏs ᴄʜᴀɴɢᴇs ɪɴᴛᴏ ᴄᴏᴍᴘʟᴇᴍᴇɴᴛᴀʀʏ ᴛʀɪɢᴏɴᴏᴍᴇᴛʀɪᴄ ʀᴀᴛɪᴏs 《sin ---> cos 》《tan -----> cot》《cosec----> sec》

$\frac{1}{ \tan(90 - theta) } = \frac{1}{ \cot(theta) }$

Hope you got it ! I tried my best
