In a ` Delta` ABC if sides a and b remain constant such that a is the error in C, thenrelatinv error in its area, is

In a triangle ABC if sides a and b remain constant such that alpha is the error in C, then relative error in its area is

In Delta ABC , the side c and angle C are constant. If there are small changes in the remaining sides and angles, then show that (da)/(cos A) +(db)/(cos B)= 0 .

If the relative error in the radius of a circle is 0.2 then the relative error in its area is

If the area of /_\ABC is calculated from the measurements of b, c, A and k is the error in A, then the percentage error in area is

In a /_\ ABC the sides b and c are given. If there is an error dA in measuring angle A, then the error da in side a is given by

If in a triangle ABC, the side c and the angle C remain constant while the remaining elements are changed slightly, show that (da)/(cosA)+(db)/(cosB)=0

If in a triangle ABC, the side c and the angle C remain constant,while the remaining elements are changed slightly,show that (da)/(cos A)+(db)/(cos B)=0

If in a triangle ABC, the side c and the angle C remain constant,while the remaining elements are changed slightly,using differentials show that (da)/(csA)+(db)/(cos B)=0

While measuring the side of an equilateral triangle an error of k% is made, the percentage error in its area
