To get the decimal think of 3/8 as a division question -3 divided by 8

3/8=0.375

now times the decimal by 100

0.375 * 100=37.5

so the answer is going to be 37.5%

The parametric curve described by the equations x=\cos(t),\;\;y=\sin(t)\cos(t) has two tangent lines at (0, 0). find the equatio

mr Goodwill [35]

Hello,

$x=cos(t)==\ \textgreater \ \dfrac{dx}{dt} =-sin(t)\\
y= \dfrac{sin(2t)}{2}==\ \textgreater \ \dfrac{dy}{dt} =cos(2t)\\

 \dfrac{dy}{dx} = \dfrac{ \frac{dy}{dt}}{ \frac{dx}{dt} } =- \frac{cos(2t)}{sin(t)} \\
For\ x=0, \ t=cos(0)= \frac{ \pi }{2} +k \pi \\

( \dfrac{dy}{dx} )_{x=0} =\pm\ 1\\

tangents \ are\ \{ y=-x,y=x \}\\
