                   f(x) = lim(n-->infinity) {[x^2] + [(2x)^2]+.............+[(nx)^2]}/n


where [.] represents greatest integer function

f(x) is continuous at:

a.){-infinity,infinity}
b.){-infinity,infinity} ~ I
c.){-infinity,infinity} ~ {0}
d.){-infinity,infinity} ~ {0,1}

lim x tends to infinity {x-(x 2 +x) 1/2 }
 
 
ANSWER -1/2 SOLUTION: lim x tends to infinity {x-(x 2 +x) 1/2 } first solve the algebra by replacing x by 1/t {1/t-(1/t 2 +1/t) ½ } {1/t-(1+t) 1/2 /t} {(1-(1+t)1/2)/t} now rationalise...

then divide the complete expression you will get the answer a 1 hey it will be then divide the complete expression by x and substiture x equals infinity you will get the answer equal to 1...

so sorry we have to rationalise it first then the term of x square will be cancelled then divide the complete expression you will get the answer a 1 approve if useful

You must add more information to the answer by providing why the slope is =1/-1 and whose slope. Let me add some more values to the answer. Any line inclined equally with axes makes angle...

tangent means slope and slope means dy/dx thus u can diffrentiate both sides and get the answer

Find all the tangents to a circle (x-a) 2 + (y-b) 2 = r 2 which make an angle @ with x axis
 
 
the result is very simple for circle centred at origin we say eqn of tangents is y=mx +/- r(1+m 2 ) 1/2 for circle with centre a,b we can linearly transform the eqn. by Replacing y------>...

sorry it must be y-b=m(x-a) +/- r(1+m 2 ) ½ ( here +/- means plus or minus) in above post g must be replaced by “-a” and m is multiplied to x-a. it was my fault But your answer is wrong as...

any line of form y-b=mx-g +/- r(1+m 2 ) ½ ( here +/- means plus or minus) will touch the given circle, if we put m=tan@ then the equation of the lines are the required tangents.

can angular momentum be a scalar ?
 
 
Generally, angular momentum is termed as vector quantity; but it is actually a pseudovector. But never it is a scaler

If sinasinb-cosacosb +1=0 prove that 1+cota tanb=0
 
 
Hint: use sina*sinb= ½ * (cos(a-b) – cos(a+b)), and cosa*cosb = ½ * (cos(a-b) + cos(a+b)), simplify and you will get, a + b = 2n*pi, just put in second equation
