If I have trinisphere in play and my opponent has goblin electromancer discounting his spells. which effect wins?
realistically speaking, which effect takes precedent over the other?
if my opponent is a storm player and wants to cast desperate ritual what would its cost be in this situation? only or ?
When determining the cost of a spell, you start with the mana cost (or alternate cost), plus additional costs. Then you apply any cost increasers, then you apply any cost decreasers. Finally, you apply any effect that affects the total cost. The Electromancer is a cost reducer, while Trinisphere affects the total cost, so you always apply Trinisphere last. If you wanted to cast the Ritual, it would cost 2R to cast (start with the mana cost of 1R, apply the cost reducer reducing it to R, then you apply Trinisphere since it affects the total cost, making the cost 2R).
601.2f The player determines the total cost of the spell. Usually this is just the mana cost. Some spells have additional or alternative costs. Some effects may increase or reduce the cost to pay, or may provide other alternative costs. Costs may include paying mana, tapping permanents, sacrificing permanents, discarding cards, and so on. The total cost is the mana cost or alternative cost (as determined in rule 601.2b), plus all additional costs and cost increases, and minus all cost reductions. If multiple cost reductions apply, the player may apply them in any order. If the mana component of the total cost is reduced to nothing by cost reduction effects, it is considered to be {0}. It can’t be reduced to less than {0}. Once the total cost is determined, any effects that directly affect the total cost are applied. Then the resulting total cost becomes “locked in.” If effects would change the total cost after this time, they have no effect.

Scientists have calculated that the chance of anything so patently absurd actually existing are millions to one. But magicians have calculated that million-to-one chances crop up nine times out of ten.
Yes, that is in effect what happens (assuming Trinisphere is untapped), since Sphere of Resistance's effect is a "cost increas[e]"an "additional cos[t]" within the meaning of C.R. 601.2f and C.R. 117.8.

if i've learned from you,
if we introduce sphere of resistance to the equation, then it and goblin electromancer cancel each other out, before applying trinisphere.
sphere first, then goblin, then finally trinisphere = cost of the spell correct?
