Answer:
(Sin(5)+5Cos(5), Cos(5)-5Sin(5), 9)
Step-by-step explanation:
The equation of tangent line is , then:
and , we have to (x,y,z) coordinates
x=r(t)+tr'(t), y=r(t)+tr'(t), z=r(t)+tr'(t); so x=Sin(5t)+t(5Cos(5t)), y=Cos(5t)+t(-5Sin(5t)), , to t=1 then:
x=Sin(5)+5Cos(5), y=Cos(5)-5Sin(5), Z=9; Finally (Sin(5)+5Cos(5), Cos(5)-5Sin(5), 9)
