If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).

We are given that:

Now we are asked to show that:

We know that:

Hence using equation (1) we get:

Also we know that:

and

so using above two formula in equation (2) we get:

( since we know that:

)

Hence we have proved that:

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
