(a) find the first 3 terms in ascending powers of x of the binomial expansion of (2+x/2)^6
(b) use your expansion to find an estimate for the value of 2.05^6

(2+x/2)^6=64(1+3x/2+15x^2/16+5x^3/16+) (2.05)^6=74.2203

Step-by-step explanation:

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
