(3) Urgent.. please help me Please do not write nonsense as an answer to get points because I WILL report you..please? Answer all if you can bc it is a lot of points.

Well you know that

sin X=Op/Hip

cos X=Ady/Hip

tan X=Op/Ady

so the first one

the second

the third

the fourth

the fifth

aprox.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
