write a general solution for
I changed sin to cos and then solved the equation and got the general solution of x = 2npi + (pi)/2 OR x= (4npi-pi)/10
Can anyone tell me if this is correct or not?
And for this question
y=5sin(3x-pi/4) has maximum and minimum values at?
Well, i said it has max and min values at y=5 and -5 and then i solved the equation
For maximum values, when y=5
I got x = [4npi+(-1)^n(2pi) +pi]/12
I would really really appreciate it if someone could check that for me and tell me if it's right or wrong
