Question

If tan(x+50)=cotx a value of x is...
Explain please

Answer 1

isn't there an identity formula for tangent and cotangent you can use?!

Answer 2

Convert into sin and cos first.

Answer 3

Then you will end up with an angle sum formula.

Answer 4

I think you'll need to use \[
\sin(a+b) = \sin(a)\cos(b) - \sin(b)\cos(a)
\]

Answer 5

wio...
wouldnt it be much easy if u write
cot x = tan ( pi/2 -x)
then u have the expression
tan (x + 50) = tan ( pi/2 - x)

so u can solve it directly.... or u can use the formula and find whole set of answers ? :)
