Answer:
cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...
Step-by-step explanation:
But that's what I say personally
Yes it is. log(1) and ln(1) both equal zero. But you cannot take the logarithm of 0.
8 is slope 50 is y-intercept
Answer:
-7 7/15
Step-by-step explanation:
-11 2/3 -(-4 1/5) = -11 2/3 + 4 1/5. Now, we need to find the LCM of 3 and 5. The LCM of 3 and 5 is 15 because 15 is the lowest number that can divide both 3 and 5 separately and both results will still be whole numbers.
Now, we have -11 10/15 + 4 3/15.
-11 10/15 + 4 3/15 = -7 7/15.
