problem with equation curve

[etehad2000]

Hi, I try to draw a curve with this formula in 2d sketch. I use equation curve in cartesian. But it draws a line instead of curve! what is it I am doing wrong?

Can you post your attempt

Hi! You may want to check the unit consistency. Make sure each term in the equation results in a consistent unit. Also, the two sides of the equation share the same unit. As Brad mentioned here, please share your attempt. The forum experts can help take a further look.

Many thanks!
