Question

find all solutions of the equation: secx-tanx=cosx

Answer 1

\[secx-tanx=cosx\]

Answer 2

\[or, 1/cosx-sinx/cosx=cosx\]

Answer 3

\[(1-sinx)/cosx=cosx\]

Answer 4

\[1-sinx=\cos ^{2}x\]

Answer 5

\[or, 1-sinx=1-\sin ^{2}x\]

Answer 6

\[1-sinx=(1-sinx)(1+sinx)\]

Answer 7

\[or, (1-sinx)(1+sinx)-(1-sinx)=0\]

Answer 8

ok :) and is that it?

Answer 9

\[(1-sinx)(1+sinx-1)=0\]

Answer 10

if
\[1-sinx=0\]

Answer 11

\[or, sinx=1\]

Answer 12

\[or, sinx=\sin90\]

Answer 13

\[or, x=90\]

Answer 14

or
\[sinx=0\]

Answer 15

\[or, sinx=\sin0\]

Answer 16

\[or, x=0\]

Answer 17

okay :) and thats the final answer?
