Function:
f(x) = 2 cos x +1
Note: The values of x should be given in radians.
Therefore;
Substituting for x = 1.5 radians
f(1.5) = 2 Cos 1.5 + 1 ≈ 1.1415
f(x) = 2 cos x +1
Note: The values of x should be given in radians.
Therefore;
Substituting for x = 1.5 radians
f(1.5) = 2 Cos 1.5 + 1 ≈ 1.1415
Answer:
1.1414
Step-by-step explanation:
Given that f is a function given by
f(x) =2cosx +1
Here x is taken in radians.
Hence when x =1.5
we have cos 1.5 = 0.0707
2cosx = 0.1414
And hence
2cosx+1=1+0.1414
=1.1414
Thus we get
f(1.5) = 1.1414 apprxy
