यदि `alpha = 112^(@) 30^(@)`, तो `sin alpha ` और `cos alpha ` के मान निकालें

If alpha = 112^(@) 30' , find the value of sin alpha and cos alpha

If alpha = 112^(@) 30' , find the value of sin alpha and cos alpha

If alpha = 112^(@) 30' , find the value of sin alpha and cos alpha

If alpha=112^(@)30', find the value of sin alpha and cos alpha.

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:

tan theta = (sin alpha-cos alpha) / (sin alpha + cos alpha)

(sqrt2 - sin alpha - cos alpha )/( sin alpha - cos alpha)=

(sqrt2 - sin alpha - cos alpha )/( sin alpha - cos alpha)=

Prove that sin ( alpha + 30^(@)) = cos alpha + sin (alpha - 30^(@))

(( cos alpha - cos 3 alpha ) ( sin 8 alpha + sin 2 alpha ))/( ( sin 5 alpha - sin alpha ) ( cos 4 alpha - cos 6 alpha ))=
