Question

simplify the expression:-
tanx+sinxsecx/cscxtanx

Answer 1

@Hero

Answer 2

help

Answer 3

rewrite everything in terms of sine an cosine
then do a little algebra

Answer 4

\[\frac{b}{a}+\frac{b\times \frac{1}{a}}{\frac{1}{b}\times \frac{a}{b}}\] where \(a=\cos(x)\) and \(b=\sin(x)\)

Answer 5

no actually it would be
\[\frac{b}{a}+\frac{b\times \frac{1}{a}}{\frac{1}{b}\times \frac{b}{a}}\]

Answer 6

k let me try nd tell u if i have any questions

Answer 7

i still don't get it

Answer 8

\[\frac{b}{a}+\frac{b\times \frac{1}{a}}{\frac{1}{b}\times \frac{b}{a}}\]
\[=\frac{b}{a}+\frac{\frac{b}{a}}{\frac{1}{a}}\]
\[=\frac{b}{a}+\frac{b}{a}\times \frac{a}{1}\]
\[=\frac{b}{a}+b\]

Answer 9

so you get
\[\tan(x)+\sin(x)\]

Answer 10

can u write this in sec,cos that form plz

Answer 11

that just obscures the algbra
i use \(a=\cos(x), b = \sin(x)\) that is what you need to do, write in terms of sine and cosine

Answer 12

k thank you!
