cos (alpha+beta)=(3)/(5) and sin (alpha-beta)=(3)/(5) and 0 lt alpha, beta lt (pi)/(2) then sin 2 alpha=

For alpha and beta both being acute angles, it is given that sin (alpha+beta)=1, cos (alpha-beta)=1/2 . The value of alpha and beta are: alpha और beta दोनों न्यून कोण है, और यह दिया गया है कि sin (alpha+beta)=1, cos (alpha-beta)=1/2 है। तो alpha और beta का मान क्या होगा?

Statement-I : If f(theta)=(cot theta)/(1+cot theta) and alpha+ beta=(5pi)/(4) then f(alpha) f(beta)=(1)/(2) Statement-II : If alpha+ beta=(pi)/(2) and beta+ gamma= alpha then tan alpha= tan beta+ 2tan gamm Statement-III sin^(2) alpha+ cos^(2) (alpha+ beta)+2 sin alpha beta cos (alpha+beta) is independent of alpha only

If sin alpha=1/2 and cos beta=1/2 then alpha+beta=

If alpha+beta=90^@ , and alpha=2 beta , then the value of 3 cos^2 alpha-2 sin^2 beta is: यदि alpha+beta=90^@ , और alpha=2 beta , तो 3 cos^2 alpha-2 sin^2 beta का मान ज्ञात करें:

If alpha and beta be between 0 and (pi)/(2) and if cos (alpha+beta)=(12)/(13) and sin (alpha-beta)=(3)/(5), then sin 2 alpha is equal to

If sin (alpha + beta)=1, sin (alpha- beta)= (1)/(2) , then tan (alpha + 2beta) tan (2alpha + beta) =

If alpha,beta in(-(pi)/(2),0) such that (sin alpha+sin beta)+(sin alpha)/(sin beta)=0 and (sin alpha+sin beta)(sin alpha)/(sin beta)=-1 and lambda=lim_(n rarr oo)(1+(2sin alpha)^(2n))/((2sin beta)^(2n))

If : sin (alpha + beta)=1 and sin (alpha-beta)=(1)/(2), "then" : tan (alpha+2beta)*tan(2alpha+beta)=
