Answer» ???diy Maths*Polynomial Sum of zeros (alpha+beta)= -b/a Products of zeroes(alpha×beta)=c/a*Linear equations in two variable - if A1/a2=b1/b2=C1/C2 then in this condition graph will coincide nd will have infintly many solutions.-if A1/a2=b1/be€(not equal to)C1/c2 then grpah will become parallel line nd will have no solution.-if A1/a2 is not equal to b1/b2 then graph will intersect nd will have exactly one solution.* Areas related to circle -Area of circle=πr2- Circumference of circle=2πr- Area of sector=thetha /360°×πr2 or- Area of sector= 1/2 × r × l - Area of segment=πr^2theta/360°-1/2r2sin thetha-Area of ring π(R2-r2)or π(R+r)(R-r)*Coordinate geometry- for a point PQ in graph PQ=√(x2-x1)^2+(y2-y1)^2#TrignometrySin = 1/cosecCos =1/secTan=1/cot Tan = sin/ cosCot=cos/sin*IdentitiesSine^2theta +cos^2thetha =1 Sorry if I have written any formula wrong ....nd hope it helps!! |
