द्विघात बहुपद `x^(2)-3x-4` के शून्यांक `alpha, beta` हो, तो `alpha+beta+alpha beta` का मान होगा

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?

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:
