Answer 1

Answer:

tan 90=sin90/cos90

Φ =1/0

Φ=Φ

hence proved

madm so easy

solve mine questions please

Answer 2

Answer:

In an x-y coordinate system, when a line makes an angle of 90 degrees from the x-axis , it is parallel to the y-axis and it would meet the y-axis at an infinite distance. Hence, tan90= infinity. tanθ=sinθ/cosθ. tan 90=sin90/cos90 = 1/0 = indeterminate.
