Question

Why these formulae are contradicting each other

Answer 1

First of all I must appreciate your question it even confused for once but your approach of writing that formula is wrong

you wrote 1 in the place of both radian measure(RM) and degree measure(DM)

but that formula is used to calculate RM if DM is given or DM if RM is given

1radian =180/pi

and 1degree=pi/180

is indeed correct but the way you placed it in the formula is implying that 1 degree is equal to 1 radian

just think about it again and if still not understood comment me i will explain it more thoroughly

i hope that's what you were asking
