" (ii) "(tan theta+2)(2tan theta+1)=5tan theta+2sec^(2)theta

Prove (tan theta+2)(2tan theta+1)=5tan theta+2sec^(2)theta

(tan theta + 2) (2 tan theta + 1) = 5 tan theta + sec^2 theta . Write 'True' or 'False' and justify your Solution.

(2 sin theta * tan theta (1- tan theta ) + 2 sin theta sec^(2) theta )/( (1+ tan theta)^(2))=

(2sin theta tan theta(1-tan theta)+2sin theta sec^(2)theta)/((1+tan theta)^(2))=(2sin theta)/(1+tan theta)

If a chord joining P(a sec theta, a tan theta), Q(a sec alpha, a tan alpha) on the hyperbola x^(2)-y^(2) =a^(2) is the normal at P, then tan alpha is (a) tan theta (4 sec^(2) theta+1) (b) tan theta (4 sec^(2) theta -1) (c) tan theta (2 sec^(2) theta -1) (d) tan theta (1-2 sec^(2) theta)

(1+tan^(2)theta)=sec^(2)theta

Prove that :1+tan theta tan2 theta=sec2 theta

Prove that cos theta (tan theta +2) (2tan theta +1) = 2 sec theta + 5 sin theta

prove that 1+tan theta tan2 theta=sec2 theta

prove that (tan theta) / (sec theta -1) = (tan theta + sec theta + 1) / (tan theta + sec theta - 1)
