Question

Help I have an assigment due at midnight and I am lost. I can get the answers in decimal but not sure how to get in fraction.
Evaluate the following. Give your answer as fractions; NO DECIMALS.
If sin t = 3/5 and the terminal point of is in quadrant II, then fill in the following values.
cos t =
tan t =
cot t=
sec t =
csc t =

Answer 1

you have a 3-4-5 right triangle, so take the ratios, and make sure to know that in quadrant II sine is positive, cosine is negative, tangent is negative, etc

Answer 2

\[\cos(t)=-\frac{4}{5}\]
\[\tan(t)=-\frac{3}{4}\] etc

Answer 3

how did your know it was a 3-4-5 triangle??

Answer 4

sin=opposite/hypotenuse
so he knows the longest side is 5 and one of the sides is 3 and using pythagoreans theorem he deduced the last side is 4
