Confuses how my teacher got this?
The question says "Given that cos(theta)=(-7/25) and sin(theta)>0, calculate the exact values of tan(theta) and csc(theta). We start out by drawing a triangle. 25 is on the side of the hypotenuse and -7 is on the adjacent side, because cos is adjacent over hypotenuse. ...

My teacher asked for the EXACT VALUES of sin(pi/6) cos(pi/4) csc(pi/3) I have to figure it out without a calculator? Also, if I was to do with it with a calculator, would csc be typed as 1/sin?

Could you tell me why you squared those numbers? Is there a formula? If I was doing sin instead, would 1^2 +y^2=√6^2 be in a different order? Also how did you get the 5? Isn't the square of 6 to the second power just 6?

Calculate the exact values of the cot(theta) and sin(theta) for the acute angle theta if sec(theta)= the square root of 6. Thank you so much!

Math
If I was converting radians to degrees would it be degrees x pi/180? Convert to radians: 180 degrees. So would the answer be 144pi/180? Which is 2.513?

Math
Convert to degrees: (5pi/8) How would I do this?

Thank you so much! :)

Physics (balancing one chemical equation)
Hi :), Please help me balance this equation I would really appreciate it! :) CS2(g)+ O2(g)----> CO2(g)+ S2O4(aq)+HEAT Thank you in advance! :)

science
I have to do a poster with the theme "Soil to Spoon" dealing with soil,forests and related to natural resources. Would you have any sugestions or links that would help me get started with this projest? Thank you for your help.
