What is the difference between sin30 and sin 30 degree
Hi!Currently,I am studying trigonometry,and I bought a new Texas Instrument Calculator that was made in China.But When I input sin (30),it gave me an answer of -0.9880316241.That is freaking incorrect.But trickily,when I input sin (30ْ),it gave 0.5 which is a correct one.Additionally,I need to work on huge math packet everyday; so I want to get it done as fast as possible.And I at least need to press four keys to input the degree symbol,it slows my progress down.And go back to the question,are they equal?Or how do they differ.sin30 &sin30ْ,thank you

because your calculater is in radian mode instead of degree .so when you input sin 30
it means 30 radian which is of course not equal to 30 degree.
so just change it into degree mode ...then you don't need to press 4 keys.
