Question

prove:
sin y+tan y/ over /1+ sec y =sin y

Answer 1

Like this? \(\dfrac{\sin y + \tan y}{1 + \sec y} = \sin y\)

Answer 2

yes

Answer 3

Start with this:

\[ \dfrac{\sin y + \tan y}{1+\sec y} \cdot \dfrac{1-\sec y}{1-\sec y} \]
Then multiply both fractions together then simplify.

Answer 4

Get it?

Answer 5

yep

Answer 6

Oh, and remember these trigonometry identify: 1−sec²x = −tan²x

Answer 7

Please let me know when you are stuck, ok?

Answer 8

yea im bad at math so im stuck

Answer 9

In what step are you stuck at?

Answer 10

just cant do it
