Question

Find the maximum and minimum value of 7 cos x + 24 sinx?​

Answer 1

Step-by-step explanation:

minimum = - √ a^2. + b^2 = - √ 25^2= - 25

maximum = √ a^2 + b^2 = 25 .......

Answer 2

Answer:

31 , -31

Step-by-step explanation:

Maximum value of sin x is 1 when θ = 90 ˚

Minimum value of sin x is –1 when θ = 270 ˚.

So, the range of values of sin x is –1 ≤ sin x ≤ 1.

Similarly range of values of cos x is – 1 ≤ cos θ ≤ 1

• So, here max. value = 7(1)+24(1)= 31
• min. value= 7(-1)+24(-1) = -31
