without using a calculator find sin beta and cos beta if tan beta=3/4 and sin beta= >0.
think of a 3 - 4 - 5 right triangle, take the appropriate ratios
how did you get 3-4-5?
|dw:1347251372575:dw|
oh wait isn't tangent like the adjacent angles or something?
you have tangent it \(\frac{3}{4}\) draw the above triangle, you get the hypotenuse is 5 either by pythagoras or by memory
no, it is not adjacent angles. if you are using right triangle trig, tangent is the length of the "opposite" side over the "adjacent" side
okay umm so whats sin?
