Zain bhai tan inverse 2 voer 4 ka answer 0.4636 hai ye shayad mera theek nhi a rha plz check this

sajida Rasheed bro apka wrong arha hai mera correct hai menay calculator se kiya hai and gain check b krliay hai

ok thanks

sajida Rasheed wellcome and sorry sis menay bro keh diya ap ka name menay jaldi men sajid read kiya

from where have you got this formula of "fai" (sorry the math type equation was not being pasted here)
as for the handouts i have not read this formula in them in the topic of conversions. kindly let me know.
it was written for conversion as :
(r,theta,z) convert to (ro,theta, fai)
and there theta=theta then why we have applied the formula of tan? wasnt it meant for fai?

noor fai= fai am just convert pi/2 radian in to  degree pi/2 is equal to 90 degree

phi is not equal to phi. theta is equal to theta and phi is equal to inverse of tan multiplied by r over z.

isnt this so?

noor check this example and follow 

i dont know from where you have dug these formulas but in handouts page number 20 it is clearly stated that theta=theta and phi=tan inverse (r/z)

and google them once too.. you'll see for yourself
