Given tan(theta) = 4/3 and pi < theta < (3pi)/2, find cos(2theta).

Step-by-step explanation:

Given:  and  

To find:

Now as we know

So we have

Therefore d. is the correct option

Hence ,

your answer would be b

step-by-step explanation:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
