What is the difference between sin30 and sin 30 degreeHi!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 pre
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
嗨！目前，我学习三角，我买了一部新德州仪器计算器这是国产。但是当我输入罪（ 30 ） ，它给了我一个答案的-0.9880316241 。这是跌下公司
我不懂,为了帮助大家，我翻译一下：
之间的区别是什么sin30和罪恶30度
嗨！目前，我学习三角，我买了一部新德州仪器计算器这是国产。但是当我输入罪（ 30 ） ，它给了我一个答案的-0.9880316241 。这是再用不正确的。但是trickily ，当我输入罪（ 30 ） ，它使0.5这是一个正确的。此外，我需要工作，巨大的数学包日常;所以我希望能做到尽快。我至少需要按四个键输入程度的象征，它的进展缓慢下降。回去的问题，他们是平等的？或者他们如何不同。 sin30 ＆ sin30 ，谢谢你
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.
