Vertices of a variable triangle are `(3,4); (5costheta, 5sintheta)` and `(5sintheta,-5costheta)` where `theta` is a parameter then the locus of its circumcentre is

Vertices of a variable triangle are (3,4);(5cos theta,5sin theta) and (5sin theta,-5cos theta) where theta is a parameter then the locus of its circumcentre is

Vertices of a variable triangle are (3,4); (5costheta, 5sintheta) and (5sintheta,-5costheta) where theta is a parameter then the locus of its orthocentre is a. (x+y-1)^2+(x-y-7)^2=100 b. (x+y-7)^2+(x-y-1)^2=100 c. (x+y-7)^2+(x+y-1)^2=100 d. (x+y-7)^2+(x-y+1)^2=100

Vertices of a variable triangle are A (3,4),B(5costheta, 5sintheta) and C (5sintheta,-5costheta) where theta is a parameter then, find the locus of its orthocentre.

If 3sintheta+5costheta=3 , then 5sintheta-3costheta=?

(costheta + isintheta)^4/(sintheta + icostheta)^5 is equal to.

(costheta + isintheta)^4/(sintheta + icostheta)^5 is equal to.

(costheta + isintheta)^4/(sintheta + icostheta)^5 is equal to.

If 3sintheta+4costheta=5 ,then 4sintheta-3costheta=

The locus of the point (a(costheta+sintheta),b(costheta-sintheta)) , where theta is the parameter, is

If sintheta+costheta=(7)/(5) , find sintheta.costheta .
