I solved it. Here are pictures: Also, I am physics major and I am taking trigonometry class (hopefully I'll pass).

I got a C in exam 1 which is worth 16%. I got D for first exam in another class. I don't know too much about another grades as I am still waiting but I have strong feeling I did terrible :( There's tutors but only very few who really did help me, some of the tutors couldn't help me. The tutors...

Hello, I am an undergraduate at UNLV. Before, I was at a community college for a few years before I went to UNLV. I used to be art major for a few semester but I didn't like it very much so I changed it to general education as I wasn't sure what I wanted to do. Last year, I thought of becoming...

I see. Do I multiply both numerators and denominators with the least common denominators?

That's good to hear that #1 and #3 is better. I am not a good writer... And about #1?

Sorry again. I am terrible at writing! ((cos θ/(1+sin θ )- (cosθ/(sinθ-1))))^-1 is this clear

I am sorry about the confusion. I should have double check my writing. 1) The expression (tan^3 θ) + (sinθ/cosθ) is equal to2) Simplify ((cos θ/1)+ (sin θ - cosθ/sinθ-1))^-1 3) The expression (cot θ)/(csc θ-sin θ) is equal to; Is that clear?

I have re-post this forum as I should have paid closer attention to rules. I apologized for that. Homework Statement 1) The expression tan^3 θ + sinθ/cosθ is equal to: (a) cot θ (b) tan θ sec^2 θ (c) tan θ (d) sin θ tan θ (e) tan θ csc^2 θ 2) Simplify (cos θ/1+ sin θ - cosθ/sinθ-1)^-1 (a)...
