Using the substitution method to solve the indefinite integral, SiNx ^ 5 + SiNx, the answer is - 2cosx + 2 / 3cosx ^ 3-1 / 5cosx ^ 5 + C,


=-(1+sinx^4)d(cosx)
=-[1+(1-cosx^2)^2]d(cosx)
=-(1+1-2cosx^2+cosx^4)d(cosx)
=-2cosx+2/3cosx^3-1/5cosx^5+c



(- 11 5 / 6) + (- 8 4 / 5) - (- 12 2 / 3) is it equal to - 7 29 / 30


(- 11 5 / 6) + (- 8 4 / 5) - (- 12 2 / 3)
=-11-8+12+(2/3-5/6-4/5)
=-7+(20/30-25/30-24/30)
=-7-29/30
=-7 and 29 / 30
That's right



If x is known to be an acute angle, what value can SiNx + cosx get from the following values
three-fourths
four-thirds
five-fourths
a half
It's better to have a process
Why have a root


My method:
First, square the original formula to (SiNx) ^ 2 + (cosx) ^ 2 + 2sinxcosx = 1 + sin (2x)
Then x is an acute angle, so 2x is an open interval from 0 ° to 180 ° and the range of sin (2x) is (0,1]
The range of the formula is (1,2]
So, to go back to the original formula is to open a root. Because x is in a quadrant, that is to say, it is all positive, and it also opens a range of positive numbers
That is, (1. Under the root sign, 2]
You've got five fourths of them
Of course, you square the original formula first. In order to get back to the original range, you have to open a root



How to calculate 27 times 125 in a simple way
This is a question of grade four in primary school: 27x125 = - O - / (the slash indicates division sign)___
Note: fill in numbers on the horizontal line and operation symbols in the circle


27x125=27x1000/8=27000/8=3375



For the straight line intersection ellipse x ^ 2 / 4 + y ^ 2 = 1 with inclination Π at two points a and B, find the trajectory equation of the midpoint of line AB?


It is known that the intersection ellipse x ^ 2 / 4 + y ^ 2 = 1 with an inclination angle of 45 degrees is located at two points a and B. find the line segment ab. let the line L: y = x + K be substituted into the elliptic equation to get (x + k) ^ 2 + x ^ 2 / 4 = 1, solution - radical 5 "K"



1.2 divided by 4 equals 0.3. Is 1.2 a multiple of 4?


No, multiples must be integers, otherwise they will be meaningless



It is known that the parabola y = x ^ 2 + 2x + m intersects the X axis at points a (x1,0), B (x2,0), (x2 > x1)
(1) Given the point P (- 1,2) on the parabola y = x ^ 2-2x + m, find the value of M;
(2) If the parabola y = ax ^ 2 + BX + m and the parabola y = x ^ 2-2x + m are symmetric with respect to the Y axis, and the points Q1 (- 2, Q1) and Q2 (- 3, Q2) are all on the parabola y = ax ^ 2 + BX + m, then the size relationship between Q1 and Q2 is______ ;
(3) Let the vertex of the parabola y = x ^ 2-2x + m be m. given that △ AMB is a right triangle, find the value of M


(1) (1) & # 178; - 2 × (- 1) + M = 2, the solution is m = - 1 (2) from the meaning of the title, the symmetry axis of y = x ^ 2-2x + m is x = 1 ?, the parabola y = ax ^ 2 + BX + M and the parabola y = x ^ 2-2x + m are symmetric about y axis, and the symmetry axis of y = ax ^ 2 + BX + m is x = - 1 ? - 2 > - 3 ?
