Question

Please help!
Let theta be an angle in quad. 2 such that sin theta = 3/5.
Find the exact values of sec theta and tan theta.
Sec theta=?
Tan theta=?

Answer 1

First let us get the hypotenuse = √{(-5)²+3²} =√34

so cos Ө = -5/√34 since Ө is quadrant II angle
sin Ө = 3/√34
sec Ө is reciprocal of cos Ө = √34/5

and tan Ө = -3/5

Answer 2

the hypot is no sqrt34

Answer 3

consider:

sin^2 + cos^2 = 1

Answer 4

don't forget the most famousest right triangle of the all
the granddaddy right triangle, the mother of all right triangles

Answer 5

a square?

Answer 6

in fact it is so famous, that it leaves its imprint on any other right triangle with integer sides

Answer 7

all i can think of is: oh no, there goes tokyo, go go godzilla; which then leads me into , everybody was kungfu fighting

Answer 9

mkty was on a good track except that sin is defined as over/hypot

3 is a leg and 5 is the hypot

Answer 10

and therefore the other side is 4, as pictured
now take your ratios from that one
