Sebastian Wright
I solved for the figure of sin 43 and cos 61 and follow the prompts getting my answer 0.9703 I just want to be sure if I did the right step

$\begingroup$The answer is $\sin(104)$ regardless of which units are used, radians or degrees.
In degrees, the OP's attempted answer $0.9703$ is correct. In radians, the answer would instead be $-0.3216$.
