Question

Did I do this proof correctly?
cos(-Θ)/1-sin(-Θ) = secΘ+tanΘ
cosΘ/1-sinΘ
cosΘ/1 - cosΘ/sinΘ
= secΘ+tanΘ

Answer 1

you need better use of paranthesis/brackets

Answer 2

andno

Answer 3

use t, or x , or a instead of the theta, makes typing easier

Answer 4

oh i see okay

Answer 5

(cos a)/(1-sin a)
(cos a/1)-(cos a/sin a)

Answer 6

fractions ....

\[\frac{a}{x+y}\ne\frac ax + \frac ay \]

Answer 7

ohh but if it was (x+y)/a then it would equal (a/x)+(a/y) ?

Answer 8

almost ...

if it was (x+y)/a then it would equal (x/a)+(y/a)
^^^^^^^^^

Answer 9

Okay thank you! Just wanted to check

Answer 10

yep
