Solve the following equation 8 cos x(2x-5)=3 and provide the general solution in radians

Answer 1

Is it

8 cos [ x(2x-5)] = 3

or

8 (cos x)(2x-5) = 3

in either case, you are going to have to

find the solutions numerically over an specific interval

for example in the latter case the first few solutions are

1.876

2.165

4.794

7.819

11.018

14.121

17.291
