42. Um, I guess it's from two swan elasticity of demand was discussed in chapter six on application of the derivative where it was defined us. Okay, we got this equation for demand. Q and Price Peak. Find the general demand equation. Q equals FP for each elasticity function hint set each elasticity function equal to get that want. So for Q Okay, so we've got e. Is this for 42? Uh huh. So in 42 he is four p square over Q square by the equation equals P over. Q. Multiply sure de que over dp we want to solve for Q Mhm. So So thank you for this equation. Um, I guess we can separate variable rate. So first we can cancel. Q. Both sides multiplied Cuba side and divide people side and then become multiply Q. About four p equals negative. Q de que over dp so we can multiply DP hair. So okay, that's separate with Cain. Took were both sides. We got yeah, 2. 30 square because that day one half Q square plus yeah, and that's it. Q. You're going to be Yeah, it's all good. That's four four
Hello. The question is taken for differential equation and we have to find a solution of this differential equation. And the decision is the square minus four square into why the square minus for the whole square. And why is it that you like and or paper to do so these square minus four. Scared is equal to zero and let capital D. Is equal to be over the eggs. Okay. So it be spared for recorded zero. So we get a. D. Is B is equal to two tomato. These equal to -2 from a -2. So the solution of the situation will be why is it working A. T. To the power to its plus bx U. To the power to it plus C. Into before explanation minus to wait. No C. D. X. Exponential -2. It it is the required solution of this differential location since it is to be powerful. So they exist for solution of this solution. And this terrified solution of the differential equation. Hope this creation
Hello. So the question is taken from differential equation and we have to find a solution of this differential equation which is D four plus eight. D square Plus 16 is equal to zero into white. Okay, since I cannot be called to zero, so D four plus eight days square plus 16 is equal to zero. Like days equal to D over dx. So from here the solution we can try to test the four plus For the square plus for the square plus 16 is equal to zero. So that will be the square plus four cardboard square. That will be equal to zero. So the solution of the situation will be these equal to Y. O. To the Y. O. To And other days -1 wild. So that solution will be bye. Is it called a course? Let me like it is Because of two eggs A plus B. X. Plus. Sign up to its C. Plus the expertise required solution of this differential equation. Hope this clears your doubt and
Hello. So the ocean is taken from differential equation and we have to solve this differential equation in order to evaluate the solution while, okay so the given equation is default plus a. D. Square plus 16 in your way is equal to zero. So this whole Tom is a complete square which is the square plus four whole square into. Why is equal to do. Why cannot be equal to remove and is equal to D. By the X. So Why cannot busy? Also despair. Plus four holds very equal to zero. So that out of the situation are these equal to Y. O. To Y. O. To minus Toyota minus Toyota. Okay so we can write the solution is a plus bh course, weights plus C. Plus D eggs signed to which this is the solution of the equation. All disclosed. Your doubt and thank you.
