Question

Please determine an expression equivalent to tanx+cotx Thank you!

Answer 1

\[\tan(x)+\cot(x)=\frac{\sin(x)}{\cos(x)}+\frac{\cos(x)}{\sin(x)}\]
\[=\frac{\sin^2(x)+\cos^2(x)}{\cos(x)\sin(x)}=\frac{1}{\cos(x)\sin(x)}=\sec(x)\csc(x)\] might do

Answer 2

but how did the 1/ (cosxsinx) get to the point of secxcscx? thats the part im struggling with! =(

Answer 3

1/sinx = cscx (cosec x)
1/cosx = sec x

Answer 4

OHH!! OK!! thank you ! =D

Answer 5

because.... of what experimentx said
