Question

Find the value of the expression.
[sin(70 degrees)/cos(-430 degrees)]+tan(-70degrees)

Answer 1

@butterflydreamer Hey sorry, do you mind helping me with a couple more, I REALLY like your method of teaching.

Answer 2

well, negative angles means you're counting counter clockwise.

Answer 3

So you'd want to find the coterminal angle of -430 by subtracting \(-360^\circ\) till you find anangle between \(0~,~ 2\pi\) I believe.

Answer 4

That's one method. You can also find the radian measure by \[-430^\circ \cdot \frac{\pi}{180^\circ}\]
