Question

Find the maximum value of 5cos A+12sinA+12

Answer 1

Dear mate,

Kindly mark the answer as brainliest if you find it useful.

Here's what you were looking for:

Your expression is 5cosA+12sinA+12

See, the minimum value of sin(x) and cos(x) is -1 for both ( and ofcourse the maximum value is +1)

So for the expression to take minimum value, sin(x) and cos(x) must take their minimum value i.e. -1.

So substituting that in the equation we get,

-5 -12 +12

Which gives the answer -5.

Hope this clears your doubt.✌

Answer 2

value of cos and sin lie from -1 to 1
max value of 5 Cos A is 5
max value of 12 Sin A is 12 +12
so in total max value is 29
