It is simple...
Just take A=45°
SinA+CosA=Sin45°+cos45°=1/√2+1/√2
=2/√2=√2
similarly...
TanA+CotA
=Tan45°+Cot45°
=1+1=2..
Hence proved!!

please mark it as brainliest answer if u found this helpful !!
thanks.....could you pls solve this without taking numeral value??
u mean we should directly prove it by taking sin and cos in terms of tan and cot?
but this is the easiest method and it is correct!!
yes i understood......but by this method i will not get full marks.....if you can solve pls do this...by the way thanks again
u will surely get full marks there are number of ways in trignometric problems can be solved
ok thank you
