1. ### (sec^2y(1+cscy)-tany(secy+tany))/(cscy(1+siny))?

= sec²(y).[1 + csc(y)] → you know that: sec(x) = 1/cos(x) = [1/cos²(y)].[1 + csc(y)] → you know that: csc(x) = 1/sin(x...sin(y) = a = 1/[a.(1 - a)] = 1/(a - a²) ← memorize this result as (1) = tan(y).[sec(y) + tan(y)] → you know that: sec(x) = 1/cos(x) = tan(y).[{1/cos(y)} + tan(y)] → you...

3. ### If -5/3 tan θ and θ is in quadrant II: Find sec θ??

sec^2 x = 1 + tan^2 x = 1 +(-5/3)^2 = 34/9 sec x = - sqrt(34/9) = - sqrt(34)/3 we use the -ve sign since cos x is -ve in the quad 2

5. ### What is the csc t Sec t and how do you find it having trouble?

csc(t) = 1/sin(t) sec(t) = 1/cos(t) That angle is 360 degrees - 45 degrees = 315 degrees cos(315 degrees) = 0.7071 = sqrt(2)/2 sin(315 degres) = -0.7071 = -sqrt(2)/2 so sec(t) = 2/sqrt(2) = sqrt(2) etc...

9. ### Let (5,-3) be a point on the terminal side of θ. Find the exact values of sinθ, secθ, and tanθ?

Refer to the sketch below. We have that tanθ = -3/5, sinθ = -3/√34 and cosθ = 5/√34 Now, secθ => 1/cosθ i.e. 1/(5/√34) = √34/5 :)>
