Representation of sinA ;cosA ;tanA in terms of half angle .

Express the ratios cosA,tanA and sec A in terms of sin A.

If an angle A of a triangle ABC is given by 3 tanA+1=0 , then sinA and cosA are the roots of the equation

If 3sinA +4cosA=4, " then find " 4sinA -3cosA .

If sinA+cosA=(3)/(5) , then find the value of sinA-cosA .

In triangleABC , which is not right angled, if p=sinA sinB sinC = and q=cosA. cosB. cosC. Then the equation having roots tanA,tanB and tanC is

If tanA=3/4, find the value of 1/sinA+1/cosA OR If sqrt(3)sintheta- costheta=0 and 0^(@)ltthetalt90^(@) ,find the value of theta

If sinA=1/3 then cosA. cosecA+tanA.secA=

Prove that: (1+sinA-cosA)/(1+sinA+cosA) = tanA/2

Prove that : (sinA-cosA)(cotA +tanA)=secA-"cosec"A

If sinA, cosA and tanA are in G.P, the cos^(3)A+cos^(2)A is equal to :
