Before describing the limits of trigonometric functions, we state few theorems along with Sandwich theorem, which helps in calculating a variety of limits in subsequent chapter..

Calculation of Cell Potential - In an electrochemical cell, electrons flow from negative electrode to the positive electrode. This shows that there is a potential difference between the two electrodes. The minimum potential which causes the flow of the electrons from the negative electrod..

The graphs of the given pair of functions intersect. Calculate their points of intersection algebraically. y = x 2 - 8 y = 6 x 2 - 45 x - 8 => (0, - 8) and (9, 73) or (5, 17) and (9, 73) or (9, 73) Only or (0, 9) and (- 8, 73)..

The graphs of the given pair of functions intersect. Calculate their points of intersection algebraically. y = 5 x 2 - 7 y = - x 2 + 11 x + 14 => ( -7 6 , -7 36 ) and (3, 38) or ( -7 6 , -7 36 ) and (- 3, 38) or ( -7 6 , -7 36 ) and (3, - 38) or ( 7 6 , -7 36 ) and (3, 38)..

The graphs of the given pair of functions intersect. Calculate their points of intersection algebraically. y = x 2 y = (- 1 7 ) x 2 + ( 8 7 ) x + 48 => (7, 49) and (- 6, - 36) or (7, 49) and (- 6, 36) or (7, - 49) and (- 6, 36) or (7, - 49) and (6, - 36)..

, it is easiest to use the appropriate trigonometric relation. Finding the value of trigonometric ratios from the tables is learnt easily. Nowadays of course calculators are able to give accurate values for any degree of tan, sin or cos. It is important to keep in mind the simple a..

Principle of Moments - If a body is in equilibrium under the action of a number of forces, then the algebraic sum of the moments of the forces about any point is equal to zero. In other words, the sum of the clockwise moments equals sum of the anticlockwise moments when the body is in equ..
