okay so I just have a question about using substitution when solving limits. Say I have the function sinx/x, if i want to find the limit when x--> 0 using approximation ( i know how to prove it with the pinching theorem by the way). So if I substitute 0.0000000001 rad into the function i get something close to 1. However if i substitute that many DEGREES I am waaaaaaaayyyyy off. I know a rad is alot more than a degree but if i draw the graphs for both wouldnt i see that the limit is 1 for both the rad graf and the degree. (This isnt an actual question where i have to use substitution but i was just experimenting and am kinda wondering...). any explanations would be appreciated. thank you.
