`(cosectheta-cottheta)^2=`

Evaluate the following limits : lim_(theta to 0)((cosectheta-cottheta)/(theta))

Prove that : (i) (1)/(sectheta-tantheta)+(1)/(sectheta+tantheta)=2sectheta " " (ii) ("cosec "theta+cottheta)/("cosec "theta-cottheta)=("cosec "theta+cottheta)^(2)

cosectheta=4/5 cottheta=?

If roots of equation 3x^(2) + 5x + 1 = 0 are (sectheta_(1) - tentheta_(1)) and (cosectheta_(2)-cottheta_(2)), then find the equation whose roots are (sectheta_(1)+tantheta_(1) and (cosectheta_(2) + cottheta_(2)).

Find the value of (sectheta-costheta)^(2)+(cosectheta-sintheta)^(2)-(cottheta-tantheta)^(2) .

If x=a(cosectheta+cottheta)and y=b(cottheta-cosectheta) , then

If cosectheta-cottheta=q , then cosectheta=?

If cosectheta-cottheta=q , then the value of cosectheta is

If cosec theta-cottheta=(7)/(2) , the value of cosectheta is :

If (1)/(cosectheta+cottheta)-cosectheta-tantheta=3ksecthetacosectheta , then value of k.
