Will give brainliest! for parametric equations x= a cos t and y= b sin t, describe how the values of a and b determine which conic section will be traced. be precise with explanation !

Step-by-step explanation:

Given that a conic section has  parametric equations x= a cos t and y= b sin t,

Since only sum of squares of sin and cos =1 we find that out of conic sections, namely

parabola, circle, ellipse, hyperbola this can correspond only to ellipse or circle

Because parabola has only one variable in 2 degrees and hyperbola is difference of squares.

i) When a=b, we have this represents a  circle with radius a.

ii) When a>b, we get an ellipse horizontal with major axis horizontal and centre at the origin and vertex at (a,0) (-a,0) (0,b) (0,-b)

iii) When a <b, we get a vertical ellipse with major axis as y axis and vertices same as

(a,0) (-a,0) (0,b) (0,-b)

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4

the first one, all those points on the line just make a strait line.
