(New to Matlab) DAE system?

Hello. I'm trying to solve this problem.

    dydt = (a*y+b)*exp(c-d*(sin(t)-e*x))*h(sin(t)-e*x)

    log(x/(i*sqrt(y)-j)+1) = k*(sin(t)-(m*y+n)*x)

here t is the independent variable and x and y are depend on t and others are constants. x(t) y(t)

How can I solve this problem? (with ode15s?)

Thank you
