naa machn uba issella kiwwe sin165 = sin pi-15 kiyalane....ithin api hogatte cos 15 agayane kalin..soo kohomada sin 15 hoyaagannee//ayeth 45-30 daana wei neda

machan pi ui anshakai ekata danna epa waradi pi=~3.142 number ekak unata manine radians walin ne anshaka nam anshaka walin danna

ow ema karana puluwan natam cos(x)^2+sin(x)^2=1 use karala (x=15) sin(15) hoyagana

RHS= [cot(A).cot(B) - 1]/( cot(A)+cot(b) )
= cos(A).cos(B) - sin(A).sin(B) udai yatai sin(A).sin(B) walin wadi karana
-------------------------------
cos(A).sin(B) + sin(A).cos(B)

=cos(A+B)
---------
sin(A+B)

=cot(A+B)

y=t+60
sin(180-y)=sin [wurtha paden wena scene ekak]

.: sin(t+60)=sin(180-60-t)=sin(120-t)

139

cos(45-t)=sin(30+t)
y=30+t

sin=cos(75-y)
sin=sin(15+y)

y=n*pi+[(-1)^n]*(15+y)

30+t=n*pi+[(-1)^n]*(45+t)

yako eka hena simple ekak ne DS neda uba?
gamini sir da uganane hes da best

nnyway... its cot(x)=cos(x)/sin(x)=1/tan(x)

ioooo machn man dan dakkeeeee...sorry wenna oneee...

man kalin meka dakke cot=cot/sin=1/tan wage

passe thamaa dakke eka cot=cos/sin=1/tan kiyala.....
