Question

if sino =x/y find the value of cosox tano in terms of x and y​

Answer 1

Answer:

it is equal to value of sino ......i.e. X/Y...

because tano = sino / coso

Now coso will cancel eachother and the sino is left ....

and in question it is given that sino= X/Y

I hope you got your answer...

Answer 2

Step-by-step explanation:

sin theta =perpendicular/ hypotenuse

cos theta=base/ hyp.

from 1 eq

base= sqrt of (h^2- p^2)

base=sqrt(y^2-x^2)

so cos theta=sqrt(y^2-x^2)/y

similarly tan theta = sin theta/ cos theta

so tan theta=x/sqrt(y^2-x^2)
