यदि ` sin alpha = (m-n)/(m+n) ` सिध्द कीजिए कि:
`tan (45^(@) - (alpha)/(2)) = sqrt((n)/(m))`

If sin alpha= (m-n)/(m+n) then prove that tan(45^@-alpha/2)=sqrt(n/m)

If tan A + sin A = m and tan A - sin A = n, prove that : m^(2) - n^(2) = 4 sqrt (mn)

If 2 cos alpha = x + (1)/(x) and 2 cos beta = y + (1)/(y) , show that (x^(m))/(y^(n))- (y^(n))/(x^(m))= 2i sin (m alpha - n beta)

If m sin theta = n sin ( 2alpha + theta ) , " then " (m+n) tan alpha =

If tan alpha = n tan beta and sin alpha = m sin beta , then cos^2 alpha is

Statement I : If m cos(theta+alpha)=n cos (theta-alpha) then tan theta.tan alpha=(m+n)/(m-n) Statement II : If (sin(alpha+beta))/(sin(alpha-beta))=(a+b)/(a-b) then tan alpha.cot beta=(a)/(b) Which of the above statements is correct ?

If m cos alpha-n sin alpha=p then prove that m sin alpha+n cos alpha=+-sqrt(m^(2)+n^(2)-p^(2))

"If" (n tan theta)/(cos^(2) (alpha - theta))= (m tan (alpha - theta))/(cos^(2) theta) "then show that" tan ( alpha - 2 theta) = (n-m)/(n+m) tan alpha

lim_(alpha to 0) (sin (alpha^n))/((sin alpha)^(m))
