"यदि `A=30o` तथा `B=60o` , सत्यापित करें कि `sin(A+B)=sinAcosB+cosAsinB` (ii) `cos(A+B)

If sin(A-B)=sinAcosB-cosAsinB , then sin15^(@) will be

If A=60^(@) and B=30^(@) , verify that : (i)sin(A+B)=sinAcosB+cosAsinB (ii) cos(A+B)=cosAcosB-sinAsinB

If A=30o and B=60o ,verify that sin(A+B)=sin A cos B+cos A sin B(ii)cos(A+B)=cos A cos B-sin A sin B

If A=60^(@) and B=30^(@) , verify that : (i)sin(A-B)=sinAcosB-cosAsinB (ii) cos(A-B)=cosAcosB+sinAsinB (iii) tan(A-B)=(tanA-tanB)/(1+tanAtanB)

Taking A=60^(@) and B=30^(@) , verify that : sin(A-B)=sinAcosB-cosAsinB .

If A= 30^(@) and B=60^(@) verify that: sin (A+B)= sin A cos B +cosA sin B.

If A = 30^(@) and B = 60^(@) , verify that sin (A + B) = sin A cos B + cos A sin B.

By taking A = 90^@ and B = 30^@ , show that sin (A - B) = sin A cos B-cos A sin B.

If A=B=60o, verify that cos(A-B)=cos A cos B+sin A sin B(iii)sin(A-B)=sin A cos B-cos A sin B(iii)tan(A-B)=(tan A-tan B)/(1+tan A tan B)
