Question

show that (sin²45-tan²45)+3(sin²90+tan²30)=17/4​

Answer 1

Answer:

please follow me please follow me please follow me please follow me

Answer 2

Answer:

proof

Step-by-step explanation:

your question is a bit wrong. you may want to check that there is a ² above (sin²45-tan²45)*²*

so the answer is:

LHS= ((1/√2)²-(1)²)²+ 3(1+(1/√3)²)

( 1/2-1)²+3(4/3)

(1/4)+4= 17/4

write the rest on your own.
