Question

trace the curve x = a cos t + 1/2 a log tan2 (t/2) , y= a sin t​

Answer 1

Answer:

please refer the  attached graph

Step-by-step explanation:

In the graph we have two functions

X = $a(\cos t + \frac{1}{2}\log \tan^{2}(\frac{t}{2}))$

Y = $a\sin t$

green  Line is showing function of X

And Red Line is showing function of Y

f(y) is simple sinusoidal with constant 'a'

graph value will depend on a

if you vary the value of 'a' the graph will vary
