help with differential equationsWatch
If you are struggling to integrate the LHS, you can use the substitution of u=y+1.
The "y" circled in red should be a "u". Once you sub back in u=y+1, your final integrated equation should be:
Then put in your values of x and y (as you have done) to find the value of C.
Regarding question 6, you need to use the values you have been given of R and Theta to calculate the value of C (highlighted in yellow) to find the complete equation.
