First, we choose u=sin(x),v'=exp(x). Using differentiation and integration of standard exponential and trigonometric functions => u'=cos(x),v=exp(x). From this we use the formula for integration by par...

Photosynthesis uses light energy to produce glucose from carbon dioxide in the air and water in the soil. Glucose is then used in respiration, so if there is a reduced rate of photosynthesis, less glucose...

Difference 1. In a perfectly competitive market marginal revenue is equal to average revenue at all quantity of production and the price for all firms is set at the same value. By contrast, in a monopoly ...
