Find the equations of the tangent lines at the point where the curve crosses itself. (enter your answers as a comma-separated list of equations.) x = 2 − π cos t y = 2t − π sin t −π ≤ t < π

positive

step-by-step explanation:

the quadrant is facing upwards

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
