Question

How would I find the area under the curve withouth plotting the points? (calculus)
f(x)=sinx
x: 0, pi/4, pi/2, 3pi/4, pi
f(X): 0, √2/2, 1, √2/2, 0

Answer 1

integrate it,be carefull with negative values

Answer 2

you mean \[\int\limits_{0}^{\pi}sinxdx\] ?

Answer 3

yes

Answer 4

2

Answer 5

i got cos(pi) - cos(0) = -2

Answer 6

Well the integral of sin = -cos

-cos(pi) + cos(0) = ?
-(-1) + 1 = ?
1 + 1 = 2

Answer 7

no the integral is -cos(x)

Answer 8

right! i just realized that

Answer 9

so is that RRAM?

Answer 10

or LRAM?

Answer 11

what is RRAM?

Answer 12

lram is left hand, rram is right hand. i know that when you do left hand, you dont include the last y value, and when you do right hand, you don't include the first y value.
