Hey there. Pls help!! 78 points in total (if correct and will give brainliest) Verify the Identity.
cot(x - pi/2) = -tan

#teamtrees #WAP (Water And Plant)

tan (x + pi/2) = -cot x 

tan (pi/6 + pi/2) = -cot (pi/6) 

tan (2pi/3) = -cot (pi/6) 

-sqrt (3) = -[sqrt 3] <<< so for x = pi/6

Explanation:

Use Property:

cos(A+B)=cosAcosB−sinAsinB

A=x,B=π2

Left Side⇒cos(x+π2)=cosxcos(π2)−sinxsin(π2)

=cosx×0−sinx×1

=0−sinx

=−sinx

=Right Side

step-by-step explanation:

their are no angles. sorry cant .

what is the original number? you forgot to add it.
