Let θ be an angle in quadrant i such that θ=tan^-1(4/3). what is the value of csc θ?

answers: 3/5 , 4/5 , 5/4 , 5/3

, you so much!

If , then and so . Recall the Pythagorean identity,

lies in the first quadrant, so we know , which also means , so we should take the positive square root. Then

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
