Answer:
a) h'(t)= (6cos3t,-9sin3t,3
cos3t)
b) t=0.93994736+πn/3
c) Magnitude of h(t) is 3 which is a constant, so h(t) lies on a sphere
Step-by-step explanation:
X = 30 I think as angle on straight line = 180 so 180-103 = 77 , 30+43 = 73 , 77+73 = 150 , 180-150= 30 , then opposite angles are the same so therefore x = 30 degrees
(1) will write us of the following form

(2) [do not it need explanation]

(3) Left place variable "y" and right place, variable "x" like this

(4) Integrate both members

(5) Solve us the integrals

(6) Isolate variable "y"

C: any cosntant
