Best ResponseYou've already chosen the best response.0\[\theta = 45 \] right?

Best ResponseYou've already chosen the best response.3so now tan theta=perpendicular/base

Best ResponseYou've already chosen the best response.0okay so i need to get cot 45°, what two would i have to use

Best ResponseYou've already chosen the best response.3so cot is the inverse of tan so cot 45=1/tan 45 =1/1=1

Best ResponseYou've already chosen the best response.0okay so i can say that i got the perpendicular/base and i imputed the values, which were 1/1, resulting in one, which is 1/tan45°, the inverse of cot 45°

Best ResponseYou've already chosen the best response.0cos45 = 1/sqrt2 sin45 = 1/sqrt2 cot45 = 1/tan45 tan45 = (1/sqrt2)/(1/sqrt2) = 1 so cot45 = 1/tan45 = 1/1 = 1

Best ResponseYou've already chosen the best response.0@DanTheMan99 if I were answering, I'd just say cot(angle) = adjacent/opposite cot(45) = 1/1 cot(45) = 1 dw:1440991725602:dw

Best ResponseYou've already chosen the best response.0whats the other side called? not the perpendicular nor the base?

Best ResponseYou've already chosen the best response.0thank you, so i say i got the base and the perpendicular as the opposite/ adjacent

Best ResponseYou've already chosen the best response.3i'll tell you a rhyme which my teacher taught .this will help you to remember the trigonometric ratios

Best ResponseYou've already chosen the best response.0cot 45° = 1/ tan45° I need to get 1/ tan45°, i get the perpendicular/base with the opposite =1 with the adjacent =1 with the hypotenuse = Square root 2 i got opposite/ adjacent which resulted in 1/1(one), which is cot 45° do you think this is good
