Question

If sin(2x) = 24/25 , find cos (2x)

Answer 1

sin = opposite side upon hypotenuse...

and let the common factors of these two be called y

and since these values are used in a right angles triangle therefore let the ratio adjacent side with hypotenuse be called a..



now using pythagoras in the triangle we can get the value of the "a"....
and then just dicide it with the hypotenuse.. and u would get the value of cos(2x)

Answer 2

and the answer would come out to be
7/25 :D

Answer 3

Geniussssss thank you so mucchhhh ;)

Answer 4

u r welcome nadhira...:D
