If `tan(picostheta)=cot(pisintheta)`, then `cos(theta-(pi)/(4))=pm(1)/(2sqrt(2))`.

If tan(picostheta)=cot(pisintheta) , then cos(theta-(pi)/(4))=(1)/(2sqrt(2)) .

If tan(picostheta)=cot(pisintheta), then prove that cos(theta-(pi)/(4))=pm(1)/(2sqrt(2))

If tan(picostheta) = cot(pisintheta) and cos(theta-(pi)/(4)) = pm(1)/(lambdasqrtmu) , then the value of lambda +mu is

If tan(picostheta) = cot(pisintheta) and cos(theta-(pi)/(4)) = pm(1)/(lambdasqrtmu) , then the value of lambda +mu is

i) If A+B=pi/4 prove that: (cotA-1)(cotB-1)=2 ii) If tan(picostheta)=cot(pisintheta) , then prove that: cos(theta-pi/4)=1/(2sqrt(2))

I tan(picostheta)=cot(pisintheta), then cos(theta-pi/4) is (A) 0 (B) 1/(2sqrt(2) (C) 1/sqrt(2) (D) none of these

If tan(picos theta) = cot(pisin theta) , then cos(theta - pi/4) is :

If tan (pi cos theta)= cot (pi sin theta) , show that cos (theta-(pi)/(4))=+- (1)/(2sqrt(2))
