If in a `Delta ABC, /_ C=90^@,` then the maximum value of `sinA sinB` is

ln a triangle ABC, B=90^@ then the value of tan(A/2)=

If 0< x_1 < x_2 < x_3 < pi , then prove that sin((x_1+x_2+x_3)/3)<(sinx_1+sinx_2+sinx_3)/3 . Hence or otherwise prove that if A, B, C are angles of a triangle, then the maximum value of sinA+sinB+sinC is (3sqrt(3))/2

In any triangle ABC, if sin A , sin B, sin C are in AP, then the maximum value of tan ""B/2 is

In Delta ABC , angle B = 90^(@) find the values of : sin A cos C + cos A sin C

In Delta ABC , angle B = 90^(@) find the values of : cos A cos C -sin A sin C

In a triangle ABC , the sides a , b , c are in G.P., then the maximum value of angleB is

If in a Delta ABC, b =sqrt3, c=1 and B-C =90^(@), then angle A is

In any DeltaABC, then minimum value of 2020sum(sqrt((sinA)))/((sqrt((sinB))+sqrt((sinC))-sqrt((sinA))) must be

In a triangle ABC, C = 90^@ , then the equation whose roots are tanA, tanB is

If the median of triangle ABC through A is perpendicular AB, then the value of sinA cosB + 2sinB cosA is equal to
