From qn we get that the tangent cuts x axis hence it's y coordinate is 0 put y=0 in eqn we will get x=7 now differentiate the eqn and put value of x nd y after differentiation, nd u will get the slope of tangent now apply y-y'=dy/dx(x-x') at point (7,0) it will be the eqn of tangent

Surely. Examples are important along with misc2

Question: A cooperative society of farmers has 50 hectares of land to grow two crops A and B. The profits from crops A and B per hectare are estimated as Rs. 10,500 and Rs. 9,000 respectively. To control weeds, a liquid herbicide has to be used for crops A and B at the rate of 20 litres and 10 litres per hectare, respectively. Further not more than 800 litres of herbicide should be used in order to protect fish and wildlife using a pond which collects drainage from this land. Keeping in mind that the protection of fish and other wildlife is more important than earning profit, how much land should be allocated to each crop so as to maximize the total profit? Form an LPP from the above and solve it graphically. Do you agree with the message that the protection of wildlife is utmost necessary to preserve the balance in environment?

Answer is √2sin^-1(sinxcosx - coax) + C

K Gopika 7 years, 8 months ago

So square on both sides for the equation sin - cos =t . Last hand side it you'll get 1- 2sinxcosx with this obtain for sinxcosx in terms of t. Substitute in the integration. You'll find the answer

K Gopika 7 years, 8 months ago

Take sin -cos as t. If you differentiate this you will get the numerator. So you should bring the denominator to this form.

K Gopika 7 years, 8 months ago

Cross multiply it. You will get cos + sin by root of sin + cos

K Gopika 7 years, 8 months ago

Bring cot and tan to sin and cos form
