How can you find the diameter of the sun?

Answer 1

Tf the angular spacing of the solar disc is #alpha#. the diameter of the Sun is nearly #tan (alpha/2) # X (Earth-Sun distance), nearly...

If the angular spacing of solar disc is # 0.97995^o#, the diameter of

The Sun is almost there.

#tan((0.97995/2)^o) AU#

#=0.008552 X 149597871 km#

#=1279344 km#.

Telescopes exist that are capable of measuring angles to within 0.001".

The diameter of the Sun can be measured using various methods, including solar astrometry, helioseismology, and solar transit observations. One common approach is using the solar parallax method, which involves measuring the apparent shift in the Sun's position as observed from different points on Earth. This, combined with the Earth-Sun distance, allows calculation of the Sun's diameter.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
