4.-15<(3(x-2))/(5)<=0

The maximum value of 8 sin 4x-15 cos 4x is

Represent (15)/(4) and (-15)/(4) on the number line.

Ex.-4 Q.15-20

Express {:[(3,4),(-1,5)] as the sum of symmetric and a skew symmetric matrix.

How many distinct real numbers belong to the following collectiont {ln(4-sqrt(15));ln(4+sqrt(15));-ln(4-sqrt(15));-ln(4+sqrt(15));ln((4+sqrt(15))/(4-sqrt(15)));ln(31+8sqrt(15))}

(4(11)/(15)+(15)/(71))^(2)-(4(11)/(15)-(15)/(71))^(2) is equal to

Consider A=[[1,4],[-1,5]] . Find A^(-1)

Sum of all real values of x for which (4+sqrt(15))^(x)+(4-sqrt(15))^(x)=62 is

Verify the following:- (ii) (-15)/(4)times((3)/(7)+(-12)/(5))=((-15)/(4)times(3)/(7))+((-15)/(4)times(-12)/(5)) .
