Either can be used, but we'll use the positive one for this problem.Now, a quick look at a unit circle gives us a second solution of .Finally, all possible solutions to this equation, and hence, all the critical points of the original function are,If you don't remember how to solv...
Insert the values of ( x=1) and ( y=2) into the equation to find if the ordered pair is a solution.( (1)+2(2)=3)Simplify ( (1)+2(2)).( 5=3)Since ( 5≠ 3), there are no solutions.No solutionSince the equation is not true when the values are used, the ordere...
The Cauchy problem for the fourth-order hyperbolic equation is solved. The use of the theory of special functions made it possible to present solutions of partial derivative equations in a form convenient for the analysis. Along the way, integral convolution equations with special functions in the...
