    use the chain rule start with -sin [(1 − e^7x)/(1 + e^7x)] now u need to find derivative of expression in brackets using quotient rule

    imo, simplify \[\frac{ 1-e^{7x} }{ 1+e^{7x} }\] first, then take the derivative by using rules.

    -sin (1 − e^7x)/(1 + e^7x) * [(1+e^7x)(7e^7x)-(1-e^7x)(7e^7x)]/(1+e^7x)^2
