Explanation Given: r ( t ) = 〈 cos 2 t sin t , sin 2 t , cos 2 t cos t 〉 Radius of sphere = 1. Center of sphere = (0,0,0) Formula used: General equation of sphere is ( x − a ) 2 + ( y − b ) 2 + ( z − c ) 2 = r 2 , Where a,b,c is center of sphere and r is radius of sphere. sin 2 x + cos 2 x = 1 Calculation: First we will find equation of sphere: ( x − a ) 2 + ( y − b ) 2 + ( z − c ) 2 = r 2 ⇒ ( x − 0 ) 2 + ( y − 0 ) 2 + ( z − 0 ) 2 = ( 1 ) 2 ⇒ x 2 + y 2 + z 2 = 1 r ( t ) = 〈 cos 2 t sin t , sin 2 t , cos 2 t cos t 〉 ⇒ x = cos 2 t sin t ⇒ y = sin 2 t ⇒ z = cos 2 t cos t To show that curve lies on the sphere, we will substitute the coordinates of curve in sphere. If we get value as 0, then we can confirm that the curve lies on the sphere To determine (b) Show that curve intersects the x-axis, the y-axis, and the z-axis.
