Find the area bounded by the curve y=x^3-4x and the x axis
Can any one explain this question with fig
What is ax^2+bx+c and
What its use in factorization? ???
Plese show me
What is trig substitution
When I do 1÷((x+2)^2+3^2)
It's tan formula
I know !!!! But thx
And this question check this
∫ 1÷(x^2+4x+13)dx
How to solve this??
Ok no one can wrong my method !!!
I know
I also know half angle but why not this
t both results have the same graph ????? Where you plotted graph
Then I checked the identity and we have the same. smile
Which identity???
I solve ans is cosecx-cot x+c
1÷sin^2 (x) -cos (x)÷sin^2 (x)
By doing rationalization
1-cosx÷sin (x)^2
Then
1÷sin^2 (x) -cos (x)÷
I know half angle but why we not rationaliz
How???
But cosine(x) isn't an irrational. ??
Why we cannot multiply and divide by 1-cos (x)
I perform rationalization and ans is wrong
Evaluate
∫ (1÷(1+cos×(x))
Why we cannot rationalise it with 1-cosx
And others? ?? Things
squiggly ???
Sizzling
Delta is δ
I don't know how dy=δy
Hehe ...,,,, sorry for this how I write symbols
~~ is approximately equal to
Haha delta is £ because there is no symbol in my mob
Hi ;
Can anyone explain me these 4 steps
How
Dy=£y
Dx~~dx
F (x+£x)~~f(x)+dy
Dy=f (x)£x
How we get this?????
pi/4 and 3pi/4.
